Ni nanocatalysts modified with a Mo dopant and graphene support have been used as low cost catalyst Pt-like activity robust durability for hydrogen evolution from the hydrolysis of ammonia borane under ambient atmosphere at room temperature.
We focus on the recent advances in non-noble metal catalyst design, synthesis and applications dehydrogenation of chemical hydrides (<italic>e.g.</italic> NaBH<sub>4</sub>, NH<sub>3</sub>BH<sub>3</sub>, NH<sub>3</sub>, N<sub>2</sub>H<sub>4</sub>, N<sub>2</sub>H<sub>4</sub>BH<sub>3</sub>) due to their high hydrogen contents CO-free H<sub>2</sub>production.
Ultrafine copper nanoparticles (Cu NPs) within porous silica nanospheres (Cu@SiO2) were prepared via a simple one-pot synthetic route in reverse micelle system and characterized by SEM, TEM, EDX, XRD, N2 adsorption-desorption, CO-TPD, XPS ICP methods. The results show that ultrafine Cu NPs with diameter of around 2 nm are effectively embedded the center well-proportioned spherical SiO2 about 25 diameter. Compared to commercial supported NPs, free synthesized core-shell Cu@SiO2 exhibit...
Hydrogen (H2), a regenerable and promising energy carrier, acts as an essential role in the construction of sustainable system. Formic acid (HCOOH, FA), natural biological metabolic products also accessible through carbon dioxide (CO2) reduction, has great potential to serve prospective H2 supplier for fuel cell. Herein, ultrafine electron-rich IrPdAu alloy nanoparticles with size 1.4 nm are highly dispersed on amine-modified mesoporous SiO2 (NH2-SBA-15) used active selective catalyst fast...
Formic acid (FA, HCOOH), featured as a major liquid product of biomass processing and especially sunshine carrier, thus becomes renewable promising organic hydrogen carrier. It is highly desirable, but it remains big challenge to develop active heterogeneous catalyst with no or low content noble metals for dehydrogenation additive-free FA at ambient conditions. Herein, the first time, WOx-modified PdNi alloy nanoclusters immobilized by amino-functionalized KIT-6 (PdNi-WOx/KIT-6-NH2) are...

Abstract Ultrafine ruthenium nanoparticles (NPs) within the mesopores of SBA-15 have been successfully prepared by using a “double solvents” method, in which n -hexane is used as hydrophobic solvent and RuCl 3 aqueous solution hydrophilic solvent. After impregnation reduction processes, samples were characterized XRD, TEM, EDX, XPS, N 2 adsorption-desorption ICP techniques. The TEM images show that small sized Ru NPs with an average size 3.0 ± 0.8 nm are uniformly dispersed SBA-15....
