“…The results show that both ion exchange methods are suitable for the incorporation of uniformly distributed Cu into the zeolite structure, and the solid ion exchange method has the highest exchange percentage. Ali et al [76] prepared 30 wt% CuO 49.65 wt% ZnO 2 0.35 wt% Al 2 O 3 catalyst at glycine to nitrates (G/O) ratios between 0.1 and 1.23 through the solution combustion synthesis (SCS) method. In brief, in the experimental procedure, varying quantities of glycine were used as a fuel into a mixed nitrate precursor solution, and the generated mixture was subjected to continuous stirring.…”

The malignant environmental changes caused by the ever-increasing amount of anthropogenic CO2 emissions have been particularly prominent in recent years. To achieve carbon mitigation and carbon neutrality, CO2 hydrogenation to methanol is regarded as a promising and sustainable route. However, the development of catalysts with exceptional performance and the establishment of a clear structure–activity relationship remain formidable challenges. Considering the lack of a state-of-the-art review on the catalytic progress of CO2 hydrogenation to methanol over non-noble catalysts, we conducted a detailed review in terms of the thermodynamic analysis, catalytic development, and reaction mechanism. In this work, we mainly reviewed the latest research progress of different catalysts including Cu-based, In2O3-based, bimetallic, solid solution, and other catalysts. Meanwhile, we summarized the effects of the support materials, promoters, and preparation methods on the catalytic performance. In addition, we also summarized the possible reaction mechanisms of direct hydrogenation of CO2 to methanol. Overall, this work would be of importance for the researchers to obtain a comprehensive understanding of the design and development of efficient catalysts for CO2 hydrogenation to methanol.

“…Many catalytic active nanoparticles of transition metals, such as Pt, 1,2 Pd, [3][4][5] Rh, 6,7 Au, [8][9][10][11] Ir, [12][13][14] and Cun [15][16][17][18][19][20][21][22] have been studied extensively for catalysis as well as other applications. For instance, Ir was studied due to their high activities in ethanol oxidation reaction [23][24][25][26][27][28][29][30][31][32] and Ni for steam reforming of alkanes, [33][34][35][36] Compared to other transition metals, the abundant and cheap Cu has been used as catalysts for ethanol conversation [37][38][39][40][41][42][43][44][45][46][47] and other applications, [48]…”

To understand the interaction between the Cu clusters and the ZnO substrate, we performed density functional theory (DFT) calculations on the adsorptions of small copper clusters on the ZnO(100) surface. The PBE functional was used in the DFT calculations with a plane wave basis set. The structural changes of the Cu clusters upon adsorption on the ZnO surface were provided. Although a few different adsorption sites are available, a single Cu atom was found to be adsorbed on three positions on a ZnO(100) surface. The adsorption strength of a Cu dimer is increased with respect to the adsorption of a single Cu atom. In the adsorptions of tetramers, and pentamers, three-dimensional configurations of Cu clusters are more favorable than the planer.

The global energy crisis, stemming from the heavy reliance on depleting fossil fuel reserves, has become a critical concern for countries worldwide, including Indonesia. In recent initiatives, hydrogen gas has emerged as a promising alternative energy carrier, generated through processes like electrolysis, which breaks down compounds containing hydrogen. This research focuses on the utilization of water electrolysis using SS 316 L, Copper, and Aluminium plates with NaHCO3, NaCl, KOH, and NaOH as catalysts. The primary objective of this study is to determine the type of plate that can produce hydrogen with lower resistivity. The average power consumption for each plate is as follows: SS 316 L at 129.88 Watts, Copper at 199.41 Watts, and Aluminium at 499.45 Watts. From the research findings, it can be concluded that the use of SS 316 L plates with NaOH as the catalyst is the most effective combination in this study, as it results in higher hydrogen production with lower power consumption or greater efficiency compared to the others. In the future, it is hoped that the research can be continued using solar panels as an alternative power source to replace the electricity supply from the national grid (PLN).
