Mesoporous biochar from lignocellulosic waste was effectivelyconverted into value-added material for adsorption and photocatalyticdegradation of anti-inflammatory pharmaceuticals. Titanium dioxide(TiO2) nano spherical particles were modified with tungstophophoricacid (TPA) at 30% (w/w), and TiO2/TPA composite was immobilized onmesoporous biochar at different ratios (1:2, 1:1, 1:0.8, 1:0.7, 1:0.61:0.5) by Ulta-sound and sol-gel method for degradation of diclofenac(DIC) and ibuprofen (IBU) using simulated solar irradiation
