Treatment of the huge amount of cellulose waste is an urgent challenge. Here, cellulose waste is used to prepare photocatalyst for molecular O2activation by using a sulfuric acid-assisted hydrothermal method. The product can activate O2to produce superoxide anion (radical dotO2−), which can be subsequently used in Cr(VI) pollution remediation effectively by reducing it into Cr(III). The Cr(VI) removal efficiency can reach 90 % in 100 min. This is important to achieve sustainable utilization of O2and solar energy. Compared with glucose, cellulose is a superior raw material for the synthesis of photocatalytic acid-HTCC. It exhibits higher reduction power due to its more negative conduction band edge. This low-cost, easy to prepare, and environment friendly acid-HTCC could have promising applications in environmental treatments. This work successfully turns waste into wealth, relieving the environmental concerns of cellulose waste, and provides a way to solve the urgent environmental pollution at present.
