| Outline of Research at the Start |
This project aims to create new avenues for large-scale and well-controlled synthesis of novel hierarchical nanoporous metals-based architectures and develop new conductive "membranes" for electrocatalysts. Several novel synthetic concepts will be proposed, and optimization of the catalytic activity will be accomplished by tuning the dimension, morphology and porous size in the architectures.

| Outline of Annual Research Achievements |
We develop a sophisticated and controllable dual-reducing agent strategy to synthesize the mesoporous nickel–cobalt boron (NiCoB) amorphous alloy spheres (AASs) with adjustable compositions by using a soft template-directed assembly approach. The selective use of tetrabutylphosphonium bromide (Bu4PBr) is beneficial to generate well-defined mesopores. Our meso-Ni10.0Co74.5B15.5 AASs generate the highest catalytic performance for the hydrolytic dehydrogenation of ammonia borane (AB). Its high performance is attributed to the combination of optimal synergistic effects between Ni, Co, and B as well as the high surface area and the good mass transport efficiency due to the open mesopores.
