“…Recently, NiPt/MIL‐101/rGO has been prepared and exhibited much higher catalytic performance in difference to NiPt NPs for dehydrogenation of hydrous hydrazine at 323 K, and giving a turnover frequency (TOF) value of 960.0 hours −1 , respectively 24,25 . While numerous studies have focused on NiPt, Ni‐Cu, Ni/Ni 3 C, Ni, and Co NPs based selenide and Zn‐Ni‐P loading on g‐C 3 N 4 , graphene, and reduced graphene oxide by co‐reduction of Ni and Pd salts solution 26‐29 . However, some doping bimetallic NPs with a non‐metal element, such as B, P, and N, has rarely been reported.…”

Summary Hydrous hydrazine (N2H4∙H2O) has been considered a promising chemical hydrogen storage carrier compound due to its high hydrogen content and easy recharge as a stable liquid for transportation. NiPt, CoPt, and CoNi nanoparticles (NPs) supported on Al(OH)3 Nano sheets are prepared in this research for hydrogen production by N2H4∙H2O catalytic decomposition. Experimental results indicated that the prepared NiPt, CoNi, and CoPt NPs have superior catalytic efficiency than that of published catalysts for the N2H4∙H2O dehydrogenation. It approximately released 3 Equiv. (H2 + N2) corresponding with TOF values of 1280, 359, and 342 hours−1 at 298 K, respectively. Prepared NiPt‐Al(OH)3 and CoPt‐Al(OH)3 possess good paramagnetic characteristics and can be easy to separate and reuse by a magnet. Meanwhile, prepared catalysts also perform good recyclability and approximately 100% selectivity after five durability tests. The crystallinity and amorphous phase percentage of NiPt‐Al(OH)3, CoNi/Al(OH)3, and CoPt/Al(OH)3 were ranged from 4.29% to 15.18% and from 84.82% to 95.72%, respectively. The catalytic performance of these above catalysts can be recognized by the electronic interaction between the Al(OH)3 Nano sheet and Ni, Co, and Pt NPs. Meanwhile, the Al(OH)3 Nano sheet surface could provide strong basic active sites with corresponding synergistic cooperative influences between ultra‐fine monometallic and bimetallic NPs and Al(OH)3 Nano sheets. In summary, the prepared Ni, Co, and Pt‐based catalysts have been developed for the application of N2H2∙H2O dehydrogenation as a favorable hydrogen storage material.

The photocatalytic hydrogen evolution reaction is one of the important ways to convert solar energy into renewable hydrogen. In this work, the Co 9 S 8 hollow polyhedron was formed after sulfidation and calcination with the metalorganic framework ZIF-67. The hollow polyhedron Co 9 S 8 provides abundant support sites for Mn 0.05 Cd 0.95 S and effectively reduces the agglomeration degree of Mn 0.05 Cd 0.95 S. The Co 9 S 8 hollow polyhedron as the reaction site has a large specific surface area and a mesoporous structure, which is beneficial to the progress of the photocatalytic reaction. A series of tests showed that the introduction of Co 9 S 8 hollow polyhedron significantly improved the lighttrapping ability and exposed more reaction sites. Co 9 S 8 hollow polyhedrons are used as electron capture sites, which can effectively collect electrons and induce the interface charge transfer of Mn 0.05 Cd 0.95 S to Co 9 S 8 . Because the Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst had a strong light-trapping ability, abundant reaction sites and Co 9 S 8 -Mn 0.05 Cd 0.95 S heterojunction accelerate the separation and transfer of charges. Therefore, the hydrogen evolution rate of the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst was relatively high, which was 13.369 mmol g −1 h −1 . In addition, the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst still has good hydrogen evolution stability after four cycles. This research may supply a new idea for the preparation of high-efficiency photocatalysts with hollow structures.Novelty Statement: The Co 9 S 8 hollow polyhedron provides abundant support sites for M 0.05 C 0.95 S particles, which effectively reduces the degree of agglomeration. The Co 9 S 8 -M 0.05 C 0.95 S heterojunction catalyst not only accelerates the migration and transfer of electrons, but also provides abundant reaction sites. Therefore, the Co 9 S 8 -M 0.05 C 0.95 S composite catalyst has good catalytic activity.
