A new generation photocatalyst CuFe2O4/rGO/halloysite nanotube (HNT) was manufactured using a simple procedure in this work. Material characterisation results reveal that the CuFe2O4 active phase with size of around 30-40 nm is spread rather consistently across sandwich-like structure rGO/HNT. The material's bandgap energy 1.9 eV, which boosts capacity to function even visible light area. catal...

A horizontal drum kiln is a traditional method widely used in Southeast Asian countries for producing biochar. An understanding of temperature conditions the and its influence on biochar properties crucial identifying suitable applications. In this study, four agricultural residues (corncob, coconut husk, shell, rice straw) were production. The turned into within 100–200 min, depending their st...

The aim of this study was to produce a low-cost activated carbon (AC) from an inexpensive precursor material, corn stigmata (CS), by chemical activation at low temperatures using H3PO4, ZnCl2 and KOH. results were showed that with phosphoric acid provides adsorbent larger specific surface area (SBET) high pore size. Textural physicochemical properties ACs H3PO4 then studied in different tempera...

Pyrolysis chars derived from rice wastes were chemically activated and used in W(VI) oxyanion adsorption assays synthetic mining wastewaters. For comparison purposes, a commercial carbon (CAC) was also used. Different experimental conditions tested the assays: solid/liquid ratio (S/L), initial pH, contact time, W concentration. The porous P2C+KOH presented overall best performance both media, d...
