Regulating the phase transition of monoclinic Bi4O5Br2 through the synergistic effect of “drag force” and facet recognition by branched polyethyleneimine
Abstract:The phase transition from tetragonal BiOBr to monoclinic Bi4O5Br2 was regulated in the presence of branched polyethyleneimine (BPEI) containing massive amino groups through a hydrothermal route. Based on the crystal...
Oxygen vacancies are highly important for photocatalytic performance in bismuth oxychloride, but their preparation is limited to vacuum roasting and hydrogen annealing techniques at high temperatures (200–400 °C).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
