Description

Application

• Influences of the Reaction Temperature and Catalysts on the Pyrolysis Product Distribution of Lignocellulosic Biomass (Aspen Wood and Rice Husk).: This research assesses the impact of reaction temperature and zinc chloride as a catalyst on the distribution of pyrolysis products from biomass sources. The findings are crucial for optimizing biofuel production processes, demonstrating how zinc chloride can alter product yields and characteristics (Sun et al., 2023).


• Mechanistic study of ZnSe nanocrystal formation from zinc halides.: The study explores the mechanisms of zinc selenide (ZnSe) nanocrystal formation, particularly from zinc chloride precursors. This research is vital for applications in optoelectronics and photovoltaics, where precise control over nanocrystal properties is critical (Mingabudinova et al., 2023).
