Enhanced catalytic performance of RuNi alloy nanoclusters toward hydrolytic dehydrogenation of NH3BH3

Nest-Type ZNC⊂PtZnδ/C as a Highly Efficient Catalyst for Methanol Electro-Oxidation

“…The leaching resistance in 4 M sulfuric acid at 353 K, more harsh than the working conditions of DMFCs, is tested for catalysts of ZNC⊂PtZn δ /C and Pt 1 Zn 1 /C, and the results show that only ∼23.9 wt % Zn and ∼0.4 wt % Pt in ZNC⊂PtZn δ /C but ∼72.3 wt % Zn and ∼5.6 wt % Pt in Pt 1 Zn 1 /C were dissolved after 60 h, respectively. The dissolved Zn 2+ from ZNC⊂PtZn δ /C may be due to the destruction of Zn-N x coordination in the peripheral frameworks by the high concentration of sulfuric acid (Figure S14), which show more advantages in stability compared with the uncovered transition and noble metal alloy catalysts. , Therefore, ZNC⊂PtZn δ /C may be a practical catalyst to promote the development of DMFCs and even for green energy conversion. − …”

Recent progress in porous catalysts for dehydrogenation of ammonia borane

“…[28][29][30] Apart from their porosity tunability, tailorability, and favorable transport properties, [31][32][33] particularly, the large surface area of porous materials promotes the uniform dispersion of metallic atoms and exposes more active sites, which maximizes the utilization of active materials. 34,35 Furthermore, the porous nanostructure facilitates the contact between the catalyst and the reactant, enabling controlled mass and electronic transfer, consequently improving the catalytic activity. 36 In particular, abundant pores can play the role of physical confinement in metal nanoparticles (NPs), which can prevent the detachment and agglomeration of NPs and improve the stability of catalysts.…”
