“…10(b) and (c)). 49–51 In Fig. 10(d) and (e), by comparing the conversion rate of unsaturated organic matter for 5 cycles with the two demulsification methods, it can be seen that the addition of NaOH has little effect on the conversion rate of unsaturated organic matter, and the selectivity for hydrogenation products was basically the same (Fig.…”

“…Iron-, cobalt-and nickel-based oxides containing supports have also attracted much attention owing to their inherently high electrocatalytic performance. For example, de Oliveira et al [137] found that composites of nano nickel oxides (NiO x ) with commercial Pt/C catalyst (Fig. 8(c)) facilitate oxidation of adsorbed H atoms by the OH species at Ni sites on the Pt surface, which leads to high electrocatalytic performance.…”

Carbon-supported Pt-based materials are highly promising electrocatalysts. The carbon support plays an important role in the Pt-based catalysts by remarkably influencing the growth, particle size, morphology, dispersion, electronic structure, physiochemical property and function of Pt. This review summarizes recent progress made in the development of carbon-supported Pt-based catalysts, with special emphasis being given to how activity and stability enhancements are related to Pt–C interactions in various carbon supports, including porous carbon, heteroatom doped carbon, carbon-based binary support, and their corresponding electrocatalytic applications. Finally, the current challenges and future prospects in the development of carbon-supported Pt-based catalysts are discussed.

“…Hence, it is necessary to develop cheap and efficient non-noble metal catalysts. [14] To improve catalytic activity (CA), selectivity and conversion rate under environmental conditions are crucial to developing safe and efficient hydrogen storage. [15][16][17] In this regard, cobalt-boride (Co-B) provided an inexpensive and effective catalyst for the hydrolysis of AB, [18,19] and a wide variety of Co-B was reported for improving the hydrolysis performance, such as unsupported Co-B, [20] supported Co-B, [21] and multialloyed Co-B.…”

Co–B has outstanding catalytic activity in catalyzing the hydrolysis of ammonia borane (AB) to produce hydrogen and has been widely studied and applied. However, the high surface energy and magnetic properties of Co–B catalysts make the particles easily agglomerate and have few active sites. Herein, a novel compound Ag/Co–B/CTAB with high catalytic activity is prepared by chemical reduction. The compound Ag/Co–B/CTAB is characterized by Fourier‐transform infrared, X‐Ray diffraction, X‐Ray photoelectron spectroscopy, and transmission electron microscopy, which show that Ag+ in the compound Ag/Co–B/CTAB is reduced entirely to Ag acting as an atomic barrier to improve dispersion of Co–B due to a large specific surface area (168.8153 m2 g−1). Moreover, the performance of Co–B doped with Ag in the hydrolysis of AB is studied and the compound Ag/Co–B/CTAB has a hydrogen generation rate of 17.685 L min−1·g−1 at 30 °C with a low activation energy of 13.33 kJ mol−1. The work on the Ag/Co–B/CTAB catalyst provides an essential insight into developing efficient hydrogen‐producing catalysts by regulating the electron transfer between metal and Co–B.
