“…Renewable and clean energy has recently attracted much attention owing to the increasing demand for lowering our dependence on fossil fuels. [1][2][3] Direct methanol fuel cells (DMFC) are considered as promising green energy conversion devices due to their high efficiency, high energy density and convenient storage of liquid fuel. 4,5 In spite of many attempts in the last decade to design and fabricate non-Pt catalysts for methanol oxidation reaction (MOR) at the anode, Pt still remains the choice of preferred catalyst for DMFC.…”

Magnesium-based hydrogen storage materials are considered to be one of the most promising solid-state hydrogen storage materials due to their large hydrogen storage capacity and low cost. However, slow hydrogen absorption/desorption rate and excessive hydrogen absorption/desorption temperature limit the application of magnesium-based hydrogen storage materials. The present paper reviews recent progress in improving the hydrogen storage properties by element substitution and additives. Ball milling is the promising technology for preparing magnesium-based hydrogen storage materials. The research and development of approaches for modifying magnesium-based hydrogen storage materials prepared by ball milling is systematically expounded. It is concluded that ball milling can significantly improve the kinetic and electrochemical properties of magnesium-based hydrogen storage materials and increase the hydrogen storage capacity. In the future, the research of magnesium-based hydrogen storage materials should be developed in terms of hydrogen storage mechanism, computer design of materials and development of a more optimized catalytic system.

Graphite carbon nitride (g-C 3 N 4 ) supported PtNi alloy nanoparticles (NPs) were fabricated via a facile and simple impregnation and chemical reduction method and explored their catalytic performance towards hydrogen evolution from ammonia borane (AB) hydrolysis dehydrogenation. Interestingly, the resultant Pt 0.5 Ni 0.5 /g-C 3 N 4 catalyst affords superior performance, including 100% conversion, 100% H 2 selectivity, yielding the extraordinary initial total turnover frequency (TOF) of 250.8 mol H2 min −1 (mol Pt ) −1 for hydrogen evolution from AB at 10 • C, a relatively low activation energy of 38.09 kJ mol −1 , and a remarkable reusability (at least 10 times), which surpass most of the noble metal heterogeneous catalysts. This notably improved activity is attributed to the charge interaction between PtNi NPs and g-C 3 N 4 support. Especially, the nitrogen-containing functional groups on g-C 3 N 4 , serving as the anchoring sites for PtNi NPs, may be beneficial for becoming a uniform distribution and decreasing the particle size for the NPs. Our work not only provides a cost-effective route for constructing high-performance catalysts towards the hydrogen evolution of AB but also prompts the utilization of g-C 3 N 4 in energy fields.
