In situ construction of 3D NiMo bimetallic catalysts anchored on dendritic mesoporous silica for the upgrading of biomass derivatives

Mass-Transfer Enhancement in the CO2 Oxidative Dehydrogenation of Propane over GaN Supported on Zeolite Nanosheets with a Short b-Axis and Hierarchical Pores

“…However, S-1 and 5GaN/S-1 display type I isotherms, indicating the presence of a significant amount of micropores in the samples. , Additionally, micropores exist in HS-1, 5GaN/HS-1, HNS-1, and 5GaN/HNS-1 samples. Different from the conventional hydrothermal preparation method, the samples exhibited clear hysteresis loops at P / P 0 > 0.4, indicative of the presence of a mesoporous structure . The analysis results for textural properties are summarized in Tables and S2.…”

“…Different from the conventional hydrothermal preparation method, the samples exhibited clear hysteresis loops at P/P 0 > 0.4, indicative of the presence of a mesoporous structure. 37 The analysis results for textural properties are summarized in Tables 1 and S2. Upon loading GaN, all of the catalysts exhibited a decreased specific surface area (S BET ) compared with the corresponding zeolite supports.…”

Environmentally-friendly preparation of natural hollow carbon spheres derived from a biomass puffball for in situ upgrading of lignin-derived vanillin

“…According to a previous study, VAN was more likely to be adsorbed on the Ni-based alloying active sites. 53,54 To further clarify the VAN hydrodeoxygenation activity on the NiCu (111) alloy, a differential charge density calculation was performed and the results (Fig. 14d) revealed an obvious electron loss between the catalyst and the reaction substrates (blue: electron loss, yellow: electron gain).…”
