“…The advantages of CVD are that a smooth deposition on the surface can be obtained, the mean free path of molecules (atoms) is relatively larger, and the spatial distribution of molecules is more uniform. For example, Milad Rasouli introduced ZnO into the HZSM-5 molecular sieve by chemical vapor deposition in their experiment [46]. In addition, it has excellent product performance, but there are some problems of pollution and insufficient precision.…”

Nitrogen oxides (NOx) are very common air pollutants that are harmful to the environment and human bodies. Selective catalytic reduction with ammonia (NH3-SCR) is considered an effective means to remove NOx emissions due to its good environmental adaptability, high catalytic activity, and remarkable selectivity. In this paper, the preparation methods, types, advantages, and challenges of ZSM-5 catalysts are reviewed. Special attention is paid to the catalytic properties and influence factors of ZSM-5 catalysts for NH3-SCR. The SCR performances of ZSM-5 catalysts doped with single or multiple metal ions are also reviewed. In addition, the environmental adaptabilities (sulfur resistance, alkali resistance, water resistance, and hydrothermal stability) of ZSM-5 catalysts are discussed, and the development of ZSM-5 catalysts in denitrification is summarized.

“…Conventionally, the fabrication approaches for CO 2 reduction catalysts are wet chemistry methods, such as impregnation [18], coprecipitation [19], and ion exchange [20]. A large number of catalytic systems have been designed and produced for the CO 2 reduction process [21]. It is known that the catalytic performance of catalysts strongly depends on the metal particle size, shape, and distribution over the support; moreover, the support-metal interaction has also affected the catalytic activity and selectivity [22].…”

Supported Pd catalyst is an important noble metal material in recent years due to its high catalytic performance in CO2 hydrogenation. An fluidized-bed plasma assisted atomic layer deposition (FP-ALD) process is reported to fabricate Pd nanoparticle catalyst over γ-Al2O3 or Fe2O3/γ-Al2O3 support, using palladium hexafluoroacetylacetonate as the Pd precursor and H2 plasma as counter-reactant. Scanning transmission electron microscopy exhibits that high-density Pd nanoparticles are uniformly dispersed over Fe2O3/γ-Al2O3 support with an average diameter of 4.4 nm. The deposited Pd-Fe2O3/γ-Al2O3 shows excellent catalytic performance for CO2 hydrogenation in a dielectric barrier discharge reactor. Under a typical condition of H2 to CO2 ratio of 4 in the feed gas, the discharge power of 19.6 W, and gas hourly space velocity of 10000 h-1, the conversion of CO2 is as high as 16.3 % with CH3OH and CH4 selectivities of 26.5 % and 3.9 %, respectively.

Nano‐alloy catalysts (NACs), which differ appreciably from monometallic catalysts, take on superior intrinsic features in surface microstructure, surface electronic properties, homogeneity in nanoscale, etc., endowing them with attractive prospects in heterogeneous catalysis. In particular, methanol synthesis from CO2 exhibits high potentials in terms of alternative energy sources to fossil fuels and NACs have shown promising performance in promoting the reaction. However, there still lacks of the bottom‐up catalysts design as well as the unanimous insight regarding the mechanistic understanding. Herein, we present a comprehensive overview of the physico‐chemical properties and the fabrication approach to NACs with high catalytic performance in the CO2 hydrogenation to methanol. Additionally, the progresses of NACs were comprehensively summarized in terms of mechanisms. Finally, some thinking about the further relevant studies on NACs is outlooked with the aim to provide new insights for achieving the precise design and controllable properties of NACs.
