“…In addition to metal additives, salts and carbon materials can also be employed to enhance the hydrogen production activity of Al-based composites. Among them, salt substances include NaCl, KCl, NiCl 2 , BaCl 2 , InCl 3 , and MgCl 2 , − and carbon materials are mainly graphite, graphene, graphene oxide, cellulose, and carbon nanotubes. − The addition of salts can cut the surface of Al during ball milling and the salts are embedded in the Al matrix to prevent the formation of an oxide film. Furthermore, numerous active sites for the reaction are provided by the dissolution of salts in water.…”

Hydrogen production via Al-H 2 O reaction has potential uses in the fields of space thrusters, engines, and hydrogen fuel cells, where hydrogen production performance of Al-based composites is critical. In this study, low-cost active additives, including g-C 3 N 4 (CN) and NaCl were added to Al−In−Sn (AlIS) alloys by the mechanical ball milling method in order to substitute metal Ga and regulate the hydrogen production activity, as Ga not only increases the cost of Al-based materials but also adversely affects the recycling of products. The results demonstrate that both CN and NaCl additives can effectively enhance hydrogen production performance of AlIS in a single additive system. Further, when 5 wt % of CN and 2.5 wt % of NaCl are concurrently introduced, Al-based composites exhibit the highest hydrogen production efficiency of 94.45% at ambient temperature. The highest hydrogen production rate reaches 475 mL•s −1 •gAl −1 . Even at 2 °C, there is still 86.66% conversion efficiency. The hydrolysates of the Al-H 2 O reaction are composed of Al(OH) 3 and AlOOH, which are primarily influenced by the reaction temperature and the types of Al-based composites. The hydrolysate formation mechanism is analyzed and proposed.

This study aims to optimize hydrogen (H2) production via ethanol steam reforming (ESR) and water gas shift reaction (WGSR) pathways, focusing on minimizing CO, CO2, and CH4 emissions while maximizing H2 yield. Employing Taguchi grey relational analysis, we investigate the intricate balance between production conditions and multi-response gas generation. Utilizing Origin Pro software, regression modeling forecasts individual and overall gas generation. Our analysis identifies optimal conditions: a feed liquid flow rate of 2 mL/min, water-to-carbon ratio of 3, ESR temperature of 300 °C, and WGSR temperature of 350 °C. These conditions promise clean, efficient H2 production. Key results show the water-to-carbon ratio and ESR temperature contributing 59.22% and 32.69% to production conditions’ impact, respectively. Graphical and mathematical models validate these findings. Moving forward, further experimental validation of optimal conditions for multi-response gas generation is recommended. This study pioneers a transformative approach towards sustainable, environmentally friendly H2 production.
