Abstract
As an important component of air pollution, the efficient removal of volatile organic compounds (VOCs) is one of the most important challenges in the world. VOCs are harmful to the environment and human health. This review systematically introduced the main VOC control technologies and research hotspots in recent years, and expanded the description of electrocatalytic oxidation technology and bimetallic catalytic removal technology. Based on a three-dimensional electrode reactor, the theoretical design of a VOC removal control technology using bimetallic three-dimensional particle electrode electrocatalytic oxidation was proposed for the first time. The future research focus of this method was analyzed, and the importance of in-depth exploration of the catalytic performance of particle electrodes and the system reaction mechanism was emphasized. This review provides a new idea for using clean and efficient methods to remove VOCs.

Abstract
A series of sulphated iron-based catalysts was prepared via an impregnation method by changing the loading content of Fe3+ and SO42− on ZrO2, and their performance in the selective catalytic reduction (SCR) of NOx by ammonia was investigated. The NOx conversion exhibited large differences among the sulphated iron-based catalysts. To explore the synergistic mechanism of iron and sulphates, XRD, BET, H2-TPR, XPS, TPD and in situ DRIFTS were used to characterize the catalysts, and it was found that among all the catalysts, the NOx conversion by Fe2SZr was greater than 90% at 350–450 °C. The results indicated that the interaction between Fe3+ and SO42− can have an effect on the redox ability, acid sites, and adsorption of NOx and NH3. With an increase in the content of Fe3+, the redox activity of the catalyst and the adsorption of ammonia improved at medium and low temperatures. However, at higher temperatures, an increase in Fe3+ led to a decrease in the conversion of NOx due to the enhanced oxidation of NH3. At medium and low temperatures, an increase in the content of SO42− decreased the concentration of Fe3+ on the surface of the catalyst and inhibited the adsorption of NOx and NH3. The addition of SO42− reduced the redox activity of the catalyst and inhibited the oxidation reaction of NH3, which follows the Eley–Rideal mechanism at high temperatures, further enhancing the SCR activity of the FexSyZr catalyst. The roles of Fe3+ and SO42− are different at low and high temperatures due to their interaction. It is the appropriate contents of Fe3+ and SO42− that can result in high NH3-SCR activity at varying temperatures.![]()

Abstract
The high thermal stability of the Lewis acidic ZnCl2-1-ethyl-3-methylimidazolium chloride ionic liquid enables the in situ fabrication of hierarchical nanostructured Pd-Au bimetallic surfaces via electrochemical alloying/dealloying of (PdAu)Zn on PdAu substrate in the ionic liquid. Nanostructured PdAu samples that consist of patterned cracks and ligaments are fabricated by using potential cycling method and constant-potential electrolysis method, respectively. The effects of working temperature and amounts of the deposited Zn on the morphology of the dealloyed (PdAu)Zn nanostructure are examined. The formation of the hierarchical nanostructure is a compromise between high-surface-diffusive Au and low-surface-diffusive Pd. Whereas Au in the alloy promotes the nanostructure formation, Pd in the PdAu nanostructure protects this material from coarsening. Compared with the plain PdAu, the nanostructured PdAu surface prepared at 150 °C exhibits a significantly higher active surface area and a high capability for the electro-oxidation of glucose.

Abstract
Pd-Au/TiC electrodes with various three-dimensional structures are obtained by the pulsed potential electro-deposition in PdCl2/HAuCl4 electrolytes. The morphologies of Pd-Au/TiC composite catalysts are significantly dependent on the component of deposited solutions. The surface appearance of Pd-Au catalysts changes from rime-shaped structure, to feather-like construction, then to pineapple root-like structure and finally to flower-like configuration with the increase of PdCl2 content in electrolytes. These particular three-dimensional structures may be very suitable for H2O2 electro-reduction, which assures a high utilization of Pd-Au catalysts and provides a large specific surface area. The electro-catalytic activities of H2O2 reduction on the Pd-Au/TiC electrodes improve as increasing the Pd content in Pd-Au alloy catalysts. The pineapple root-like Pd5Au1/TiC electrode reveals remarkably excellent electrochemical property and desirable stability for catalyzing H2O2 reduction in acid media. The direct peroxide-peroxide fuel cells with a 10 cm3 min-1 flow rate display the open circuit voltage (OCV) of 0.85V and the peak power density of 56.5mWcm-2 at 155mAcm-2 with desirable cell stability, which is much higher than those previously reported.
