The production of hydrogen from biomass through thermochemical methods, particularly steam gasification, is gaining traction due to its potential for H2-rich syngas generation. However, challenges like tar formation impede the process's efficiency. To address this, Prof. Yin Jiao's team developed Ni/Ca3AlO catalysts, improving stability and performance. The catalyst exhibited remarkable cyclic stability, high hydrogen yield, and minimal carbon deposition. Its innovative morphology prevents sintering, crucial for sustained catalytic activity. The study highlights the catalyst's resistance to carbon accumulation and its potential for biomass gasification. This research contributes to advancing sustainable hydrogen production and offers insights for future catalyst design in the field of renewable energy.
