The photocatalytic TiO 2 has been regarded as a promising catalyst of nonbiodegradable organic pollutants in wastewater. Resolving some issues of agglomeration, recoverability, and poor efficiency, an inorganic TiO 2 -based catalyst has been constructed by a template method, which picks out bamboo fibers originating from processing waste. Characterization of the hollow fibrous TiO 2 /Fe 3 O 4 catalyst confirms the successful loading of Fe 3 O 4 and TiO 2 , along with a well-developed macroporous structure and high porosity (67.46%). At a solar ...
