Efficient photoelectrocatalytic performance of beta-cyclodextrin/graphene composite and effect of Cl⁻in water: degradation for bromophenol blue as a case study

Abstract

O2˙− played a crucial role in the photoelectrocatalytic degradation of BPB by the prepared GR/β-CD. Cl− marginally promoted the degradation of BPB and chlorinated intermediates were generated.

Synthesis Catalyst of Loading Nano Platinum on Graphene Nanosheets and Photodegradation of Bromophenol blue in Ultra-violet light.

“…Photocatalysts were synthesized to study the photodegradation bromophenol and reduced in wastewaters. [20][21][22] Graphene is well-known as a monolayer of sp 2 -bonded carbon atoms into a two-dimensional structure, it has been rapidly expanded interest of graphene due to its remarkable properties like high electronic and thermal conductivity, as well as features of transport and mechanical characteristics, in addition, it shows a very high surface area and the modification of textural properties of catalyst layers 23 . In this work, the catalyst nano platinum on graphene nanosheets was synthesized and tested as photocatalyst as used a bromophenol as a case study.…”

Computational Models That Use a Quantitative Structure–Activity Relationship Approach Based on Deep Learning

“…The QSAR is a method for predicting the physical properties, environmental fate, or toxicity of substances (for which there is a paucity of information available in the relevant datasets) using model formulas obtained statistically from parameters such as their physical properties [11][12][13][14][15][16][17][18]. For example, these include ecological structure-activity relationships (EcoSAR) that determine chemically acute and chronic toxicity to aquatic organisms such as fish, aquatic invertebrates, and aquatic plants; toxicity prediction using computer-assisted technology (e.g., TOPKAT) that quantifies the electronic and shape attributes of structures of possible two-atom fragments using their electrotopological state; and expert judgments about the alert structures, functional groups, and partial structures that contribute to the development of toxicity because specialized knowledge is required [19][20][21][22][23][24][25][26][27]. In contrast, the categorical approach is a method for grouping and evaluating the structural similarities of groups of substances that show similar or regular patterns of toxicity [28][29][30].…”
