Effects of amylum as capping agent in ZnO nanoparticles synthesis from spent Zn-C battery

Ultra-fast green synthesis of a defective TiO2 photocatalyst towards hydrogen production

“…31,33,50 The degree of Raman shift increased as the increase of l -As concentrations, suggesting the increase in surface O v sites. As reported by literature, the microwave-assisted method can convert l -As into carbonaceous substances such as carbon nanodot 51,52 or carbon microsphere. 38 In this work, a trace of generated carbonaceous substances was obviously detected in Raman spectra of all PAs x samples.…”
