Abstract
Inhospitable, inaccessible, and extremely remote alike the famed pole of inaccessibility, aka Point Nemo, the isolated locations in deserts, at sea, or in outer space are difficult for humans to settle, let alone to thrive in. Yet, they present a unique set of opportunities for science, economy, and geopolitics that are difficult to ignore. One of the critical challenges for settlers is the stable supply of energy both to sustain a reasonable quality of life, as well as to take advantage of the local opportunities presented by the remote environment, e.g., abundance of a particular resource. The possible solutions to this challenge are heavily constrained by the difficulty and prohibitive cost of transportation to and from such a habitat (e.g., a lunar or Martian base). In this essay, the advantages and possible challenges of integrating Fischer-Tropsch, artificial photosynthesis, and plasma catalysis into a robust, scalable, and efficient self-contained system for energy harvesting, storage, and utilization are explored.

Abstract
The degradation of phenylic contaminants (phenol, hydroquinone, nitrobenzene, p-nitrophenol) containing Cr(VI) has been investigated in a dielectric barrier discharge (DBD) system using a ZnCo2O4 composite catalyst. The ZnCo2O4 nanowires combined with multi-walled carbon nanotubes (MWNTs) on a sponge substrate in the discharge system can induce a decrease in the corona inception voltage and discharge becomes more stable resulting in an improvement in the energy utilization efficiency. With the synergistic degradation of phenylic species containing Cr(VI), the total elimination efficiency was further improved. The active substances (H2O2 and O3) were detected in the discharged solution, and some of them were consumed in the phenylic system. The effects of ·OH, O2·- and e- were also verified using free radical trapping experiments in which ·OH exhibited the main oxidation effect for the degradation of phenylic pollutants, and e-, H2O2 and H· affect the reduction of Cr(VI). The intermediate products were determined in order to analyze the degradation process of phenylic pollutants by the ZnCo2O4 composite catalyst in combination with the DBD system. The electron transfer process in the ZnCo2O4 composite catalyst during discharge was analyzed. Finally, the biotoxicity of the phenylic pollutants before and after degradation was compared.

Abstract
The direct activation of diluted CO2 in argon was studied in a co-axial dielectric barrier discharge (DBD) reactor powered by photovoltaic energy. The influence of the initial CO2 and argon concentration on the CO2 decomposition to form CO was investigated using a copper-based catalyst in the discharge zone. It was observed that the CO2 conversion was higher at lower CO2 concentrations. The presence of the diluent gas (argon) was also studied and it was observed how it has a high influence on the decomposition of CO2, improving the conversion at high argon concentrations. At the highest observed energy efficiency (1.7%), the CO2 conversion obtained was 40.2%. It was observed that a way to enhance the sustainability of the process was to use photovoltaic energy. Taking into account a life cycle assessment approach (LCA), it was estimated that within the best-case scenario, it would be feasible to counterbalance 97% of the CO2 emissions related to the process.

Abstract
Various carbon dioxide (CO2) capture materials and processes have been developed in recent years. The absorption-based capturing process is the most significant among other processes, which is widely recognized because of its effectiveness. CO2 can be used as a feedstock for the production of valuable chemicals, which will assist in alleviating the issues caused by excessive CO2 levels in the atmosphere. However, the interaction of carbon dioxide with other substances is laborious because carbon dioxide is dynamically relatively stable. Therefore, there is a need to develop types of catalysts that can break the bond in CO2 and thus be used as feedstock to produce materials of economic value. Metal oxide-based processes that convert carbon dioxide into other compounds have recently attracted attention. Metal oxides play a pivotal role in CO2 hydrogenation, as they provide additional advantages, such as selectivity and energy efficiency. This review provides an overview of the types of metal oxides and their use for carbon dioxide adsorption and conversion applications, allowing researchers to take advantage of this information in order to develop new catalysts or methods for preparing catalysts to obtain materials of economic value.

Abstract
Artificial photoreduction of CO2 to clean energy utilizing the unlimited solar energy has shown promise to suppress the greenhouse effect and alleviate the energy shortage. In this study, a simple one-step calcination method was utilized to synthesize ultrathin nanosheet g-C3N4 (NS-g-C3N4). The prepared NS-g-C3N4 with a thickness of 10 nm was demonstrated to exhibited higher efficiency and selectivity than that of bulk counterpart (B-g-C3N4) for the photocatalytic reduction of CO2 to CO under visible light irradiation. The yield of CO in the system with obtained NS-g-C3N4 was 5.8 times higher than that of B-g-C3N4. CO was measured to be the sole product detected in the system with NS-g-C3N4, while CO2 can be reduced into CO, CH4 and CH3OH in the system with B-g-C3N4 under the same photocatalytic reduction conditions. The ultrathin nanostructures and abundant surface defect sites of NS-g-C3N4 could enhance the visible light adsorption efficiency, favor the separation and transfer of photogenerated carriers, and provide strong chemisorption sites for CO2, and thus resulting in its remarkable photocatalytic activity to CO2 reduction. More importantly, the surface defects of nanosheet could shift the adsorption mode of CO2 from N-CO2- for the B-g-C3N4 to N-O-CO for NS-g-C3N4, and eventually contributing the selective photoreduction of CO2 to CO. The obtained also NS-g-C3N4 exhibited excellent stability for CO2 photoreduction. No significant change in the photoreduction efficiency of CO2 in the system with NS-g-C3N4 was observed after four cycles. This study could not only provide a novel strategy to realize the high selectivity and efficiency photocatalytic conversion CO2 to CO, but also aims to clarify the interactions between the adsorption model of CO2 on g-C3N4 surface and the selectivity and efficiency of CO2 photoreduction.

Abstract
Dry reforming of methane is conducted in a catalyst packed-bed dielectric barrier discharge (DBD) reactor aiming to improve the reaction efficiency. The MgO- and CeO2-promoted Ni/γ-Al2O3 catalyst is tested to carry out the reaction. An interesting observation is that Ni/MgO_Al2O3 integration provides ∼35 and 13% conversion of CH4 and CO2, respectively. The highest syngas ratio of 0.94 is obtained with Ni/MgO_Al2O3, whereas the ratio is only 0.57 with Ni/CeO2_Al2O3 and 0.64 with bare DBD. In addition, Ni/CeO2_Al2O3 offers the highest selectivity (68%) of CO due to the oxygen buffer property of CeO2. Finally, the optimal acid/base property is highly desirable for the dry reforming reaction.
