Biochar based photocatalyst for degradation of organic aqueous waste: A review

Facile Synthesis of Hybrid Nanoflowers Using Glycine and Phenylalanine and Investigation of Their Catalytic Activity

“…Many different methods have been developed for wastewater treatment, which can be grouped under three headings: physical, chemical, and biological treatment [5–9] . However, the cost of these methods is quite high and the disposal of the resulting large amount of concentrated sludge causes problems.…”

“…[1][2][3][4] Many different methods have been developed for wastewater treatment, which can be grouped under three headings: physical, chemical, and biological treatment. [5][6][7][8][9] However, the cost of these methods is quite high and the disposal of the resulting large amount of concentrated sludge causes problems. In addition, the disadvantages such as excessive use of chemicals during the application of some of them, causing a secondary environmental pollution problem, excessive energy consumption, and inability to adapt to all wastewaters with different characteristics limit the application of these methods.…”

Pollen Carbon-Based Rare-Earth Composite Material for Highly Efficient Photocatalytic Hydrogen Production from Ethanol–Water Mixtures

“… 5 , 6 Excitingly, biochar can be directly used to realize the composite with other substances for improving the electron transfer. 7 − 9 However, the current research on biochar-based photocatalysts is mainly focused on the degradation of organic pollutants, 4 , 10 , 11 and there is less research in photocatalytic hydrogen production from water. 6 , 8 , 9 , 12 − 15 Moreover, it is difficult to achieve a high catalytic effect using a simple carbon material.…”

“…At the same time, biochar can inherit the morphology and porous structure of natural biomass and realize the self-doping of elements (P, N, etc.) to improve the use of light, enhance the mass transfer, and raise the dispersion of the loaded metal. , Excitingly, biochar can be directly used to realize the composite with other substances for improving the electron transfer. − However, the current research on biochar-based photocatalysts is mainly focused on the degradation of organic pollutants, ,, and there is less research in photocatalytic hydrogen production from water. ,,,− Moreover, it is difficult to achieve a high catalytic effect using a simple carbon material.…”

Phosphorus-modified two-dimensional graphdiyne (CnH2n−2)/ZnCdS forms S-scheme heterojunctions for photocatalytic hydrogen production

“…[5][6][7] In recent years, the excellent stability and durability of carbon-based materials have gradually replaced the application of precious metals in the catalytic field, such as carbon nanotubes, carbonitride, [8][9][10] graphene, [11][12][13] C 60 , 14,15 and biological carbon. 16,17 Since the first synthesis of a new carbon material, graphdiyne (GDY), by Yuliang's group in 2010, 18,19 the scientific community has further explored it. 20,21 As a new allotrope of carbon, graphdiyne is composed of benzene rings linked with six other benzene rings through a butadiene bond.…”
