Heterostructuring 2D Co2P nanosheets with 0D CoP via a salt-assisted strategy for boosting hydrogen evolution from ammonia borane hydrolysis
Ammonia borane (NH 3 BH 3 , AB) holds promise for chemical storage of hydrogen. However, designing superb and low-cost photocatalyst to drive hydrogen evolution from AB under visible light irradiation is highly desirable but remains a major challenge for promoting the practical utilization of AB.

However, designing superb and low-cost photocatalyst to drive hydrogen evolution from AB under visible light irradiation is highly desirable but remains a major challenge for promoting the practical utilization of AB. Herein, we demonstrated a heterostructure photocatalyst consisting of zero-dimensional (0D) CoP nanoparticles immobilized on two-dimensional (2D) Co

This work not only opens a new avenue to accelerate hydrogen evolution from AB by regulating the electronic structures of heterointerfaces, but also provides a novel strategy for the construction of precious-metal-free materials for hydrogen-related energy catalysis in the future. |
