Modulation the electronic structure of hollow structured CuO-NiCo2O4 nanosphere for enhanced catalytic activity towards methanolysis of ammonia borane

Yufa Feng et al.

Summary: In this study, a non-noble-metal based hollow CuO-NiCo2O4 nanospheres composite with high catalytic activity for hydrogen production from AB methanolysis was constructed. The synergy between CuO and NiCo2O4 was revealed to promote the catalytic activity. Mechanistic studies identified the dissociation of O-H bond in CH3OH as the rate-determining step. These findings are of great importance for the rational construction of cost-efficient catalysts for hydrogen production from AB methanolysis.

Interfacial charge transfer induced dual-active-sites of heterostructured Cu0.8Ni0.2WO4 nanoparticles in ammonia borane methanolysis for fast hydrogen production

Jinyun Liao et al.

Summary: In this study, a series of cheap CuxNi1-xWO4 catalysts were designed for ammonia borane (AB) methanolysis. Among them, heterostructured Cu0.8Ni0.2WO4 exhibited the highest turnover frequency (TOF) and maintained good catalytic activity after multiple cycles. It was found that dual active sites, Cu and Ni, played important roles in the adsorption and activation of AB and methanol, respectively, leading to the enhanced catalytic activity. This study provides guidance for the development of novel catalysts with excellent performance and low cost in AB methanolysis.

In-Situ Grown Nickel-Cobalt (NiCo) Alloy Nanoparticles Decorated on Petal-Like Nitrogen-Doped Carbon Spheres for Efficient OER Activity

Zulfiqar Ali et al.

Summary: Here, we report the in-situ formation of extremely small NiCo alloy nanoparticles on nitrogen-doped carbon spheres using the CVD method. These nanoparticles showed promising electrocatalytic activity in the oxygen evolution reaction. The formation of these nanoparticles was attributed to the carbonaceous environment and the catalytic effect of the substrate. The synthesized hybrid nanocomposites exhibited better OER activity in alkaline conditions due to the synergistic contribution of their multiple components.

Porphyrin framework-derived N-doped porous carbon-confined Ru for NH3BH3 methanolysis: the more pyridinic-N, the better

Xiugang Li et al.

Summary: Encapsulating ultrafine Ru nanoparticles in N-doped porous carbon derived from a new porphyrin framework resulted in a catalyst with high hydrogen production performance and small Ru NPs size, demonstrating the crucial role of pyridinic-N in the catalytic activity. The study also showed that the cleavage of the O-H bond in methanol is involved in the rate-determining step of ammonia borane methanolysis, offering insights into designing stable and ultrafine metal NPs confined in pyridinic-N-rich composites for various applications.
