Abstract
Electrochemical reduction of CO2 to fuels and chemicals is an effective way to reduce greenhouse gas emissions and alleviate the energy crisis, but the highly active catalysts necessary for this reaction under mild conditions are still rare. In this work, we grew CuBi bimetallic catalysts on derived copper foam substrates by co-electrodeposition, and then investigated the correlation between co-electrodeposition potential and electrochemical performance in CO2-to-formate conversion. Results showed that the bimetallic catalyst formed at a low potential of - 0.6 V vs. AgCl/Ag electrode achieved the highest formate Faradaic efficiency (FEformate) of 94.4% and a current density of 38.5 mA/cm2 at a low potential of - 0.97 V vs. reversible hydrogen electrode (RHE). Moreover, a continuous-flow membrane electrode assembly reactor also enabled the catalyst to show better performance (a FEformate of 98.3% at 56.6 mA/cm2) than a traditional H-type reaction cell. This work highlights the vital impact of co-electrodeposition potential on catalyst performance and provides a basis for the modulated growth of bimetallic catalysts on substrates. It also shows the possibility of preparing Bi-based catalysts with no obvious decrease in catalytic activity that have been partially replaced with more economic copper.

Abstract
In this work, Sn species are deposited onto the surface of a Bi2O3 material by a facile disproportionated reaction and the prepared catalyst shows a superior electrocatalytic performance towards CO2 reduction. The deposition of Sn atoms can donate electrons to the Bi2O3 material and increase its electrical conductivity. The SnM-Bi2O3 catalyst with the optimal Sn content delivers a high faradaic efficiency of 95.8% at -1.0 V for formate production. In addition, the partial current density of formate can reach 41.8 mA cm-2. The SnM-Bi2O3 catalyst also exhibits superior stability towards long-term electrolysis. The modification of Sn species not only helps to stabilize the reaction intermediate but also inhibits the hydrogen evolution reaction (HER) pathway, achieving the synergetic enhancement of catalytic activity.

Abstract
Hollow fibers have attracted more and more attention due to their broad range of applications in numerous fields. We review the latest advance and summarize the fabrication methods, types and applications of hollow fibers. We mainly introduce the fabrication methods of hollow fibers, including co-extrusion/co-axial spinning methods, template methods, 3D printing methods, electrospinning methods, self-crimping methods and gas foaming process. Meanwhile, we summarize four types of hollow fibers: one-layered hollow fibers, multi-layered hollow fibers, multi-hollow fibers and branched hollow fibers. Next, we focus on the main applications of hollow fibers, such as gas separation, cell culture, microfluidic channels, artificial tubular tissues, etc. Finally, we present the prospects of the future trend of development. The review would promote the further development of hollow fibers and benefit their advance in sensing, bioreactors, electrochemical catalysis, energy conversion, microfluidics, gas separation, air purification, drug delivery, functional materials, cell culture and tissue engineering. This review has great significance for the design of new functional materials and development of devices and systems in the related fields.

Abstract
Sn-based electrocatalysts have shown great potential in the future industrial application of CO2 electroreduction (CO2 ER) to C1 products due to their non-toxicity and low price. However, it is a great challenge to fabricate a Sn-based electrocatalytic system with high performance and stability. Herein, grafted pyridine was innovatively coupled with SnO2 to construct an organic-inorganic composite (SnO2 /Py-CNTO) for highly efficient CO2 ER. The detailed studies showed that pyridine and protonated pyridine coexist on the surface of SnO2 /Py-CNTO, and both play distinctive roles in promoting the selectivity of CO2 ER. Benefiting from the merits, SnO2 /Py-CNTO delivered an excellent faradaic efficiency (FE) of 96 % for CO2 ER at -1.29 VRHE where the HCOOH production with 85 % FE dominated, and good stability for 32 h electrolysis. The theoretical calculations showed that protonated pyridine not only facilitates the CO2 adsorption and HCOOH desorption, but also significantly reduces the limiting potential for the conversion of CO2 to HCOOH.
