New composite of pecan nutshells biochar-ZnO for sequential removal of acid red 97 by adsorption and photocatalysis

Recent advancement of biomass-derived porous carbon based materials for energy and environmental remediation applications

“…The high performance was attributed to the electronic interaction between ZnO and graphitic C together with π–π conjugation system. 360 In similar studies, ZnO composites in synergy with pecan nutshell 361 and sewage sludge 362 -derived porous carbons have been explored as photocatalysts for the oxidative degradation of Reactive Red 97 and Acid Orange 7 azo dyes from aqueous solutions, respectively.…”

Solar‐light‐driven ZnO/biochar treatment of pesticides contaminated wastewater: A practical and computational study

“…24,25 The modification by BC derived from such solid waste material promotes the circular bioeconomy while also lowering overall costs. Leichtweis et al 26 used BC prepared from pecan nutshells and ZnO to degrade acid red 97, while the synthesized composite showed higher performance than the pristine ZnO. 26 Recently, computational modeling has drawn researchers' attention to the physical and chemical interactions of pollutants adsorption studies using BC.…”

Study on the Enhanced Remediation of Petroleum-Contaminated Soil by Biochar/g-C3N4 Composites

“…BC is a pyrogenic carbonaceous material produced through the pyrolysis (350–700 °C) of agriculture and forestry biomass, food processing waste, animal manure, and other industrial waste biomass under an oxygen-free environment [ 18 , 19 , 20 ], which has a wide range of sources and a cheaper cost [ 21 ]. It has good adsorption and special photoelectric properties [ 22 ]. However, BC has some disadvantages in practical application, such as poor selective adsorption, easy saturation, easy desorption, insufficient long-acting performance, and so on [ 23 ].…”
