Cu0.4Co0.6MoO4 Nanorods Supported on Graphitic Carbon Nitride as a Highly Active Catalyst for the Hydrolytic Dehydrogenation of Ammonia Borane

Abstract

As a typical chemical hydride, ammonia borane (AB) has received extensive attention because of its safety and high hydrogen storage capacity. The aim of this work was to develop a cost-efficient and highly reactive catalyst for hydrolyzing AB. Herein, we synthesized a series of CuxCo1–xMoO4 dispersed on graphitic carbon nitride (g-C3N4) to dehydrogenate AB. Among those CuxCo1–xMoO4/g-C3N4 catalysts, Cu0.4Co0.6MoO4/g-C3N4 exhibited the highest site time yield (STY) value of 75.7 m o l H 2 m o l c a t − 1 m i n − 1 with a low activation energy of 14.46 kJ mol−1. The STY value for Cu0.4Co0.6MoO4/g-C3N4 was about 4.3 times as high as that for the unsupported Cu0.4Co0.6MoO4, indicating that the g-C3N4 support plays a crucial role in improving the catalytic activity. Considering its low cost and high catalytic activity, our Cu0.4Co0.6MoO4/g-C3N4 catalyst is a strong candidate for AB hydrolysis for hydrogen production in practical applications.

A new copper molybdate-doped aluminium phosphate nanocomposite heterostructure for photoreduction of aqueous 2-NA and 4-NA

“…8 M x Al 1− x MoO 4 (M = transition metal) is mainly employed in catalytic applications and has exceptional electrical and magnetic properties. 9,10 Previously, Ghorai et al investigated the phase formation temperature and photocatalytic activity of M x Cr 1− x Mo x P 1− x O 4 (M = Co, Ni and Cu) toward p -nitrophenol 11 and thymol blue. 12 Now, we are very much interested in the new composition of M x Mo x Al 1− x P 1− x O 4 (M = Cu, Ni, and Co) and studying its photocatalytic activity, which has as yet not been studied in the literature.…”

Hydrogenation Production from Ammonia Borane over PtNi Alloy Nanoparticles Immobilized on Graphite Carbon Nitride

“…Among various hydrogen storage materials conducted, ammonia borane (AB), a white solid with excellent stability at room temperature and high hydrogen content (19.6 wt %), has aroused considerable interest as a promising hydrogen storage material [14,15]. There are two main approaches for AB to release hydrogen: (i) thermal dehydrogenation, (ii) hydrolysis dehydrogenation [14][15][16]. However, The synthesis process of PtNi/g-C3N4 is schematically emerged in Scheme 1.…”
