Because of their acute toxicity and long-lasting effects on the environment such as chemical accidents, agricultural runoff, and industrial effluents, has raised concerns around the world. Semiconductor-based photocatalysis has gained prominence for its ability to degrade organic contaminants comprehensively, providing a potential solution to the limitations of conventional methods. This study addresses the environmental repercussions of dye contamination and explores the utilization of active semiconductor photocatalysts for effective wastewater treatment. Our focus lies in synthesizing CZTS through the hydrothermal route, a method gaining traction for its simplicity and environmental viability. To augment the photocatalytic efficiency of semiconductor materials, graphene oxide (GO) has been introduced with varying GO concentrations of 5% and 10%. Additionally, the study explores the performance of CZTS nanoparticles with varying GO concentrations for antimicrobial applications against seven Gram positive/negative bacterial and one yeast strains and its catIP: 203 8 09 20 On: Tue 11 Jun 2024 13:09:34 alytic prowess in the photodegradatin of methylne blue dye under ultraviolet light.

Transfer of Cvd-Graphene on Real-World Surfaces in an Eco-Friendly Manner
(Amer Chemical Soc, 2023) Yılmaz, Kurtuluş; Gürsoy, Mehmet; Sakalak, Huseyin; Ersoz, Mustafa; Karaman, Mustafa
Here we report a one-step and all-dry transfer method for transfer of chemical vapor deposited graphene (CVD-graphene) on different application surfaces using pressure sensitive adhesive (PSA) material as the transfer medium, which is deposited on the application surface by the initiated CVD (iCVD) method in the form of a thin film. The as-deposited PSA film is a copolymer of acrylic acid and ethylhexyl acrylate, in which the relative amount of each component was shown to be a determining factor for the proper adjustment of the adhesive force required for the adhesion-based transfer process. With the help of the thin PSA film on the real-world application surface, graphene transfer was achieved with ease and at high quality by just peeling off the copper substrate, where CVD-graphene was initially deposited. With the all-dry and eco-friendly transfer procedure outlined in this study, it was possible to transfer graphene to a flexible large-area PET substrate (10 cm x 10 cm) on which higher conductivity values were obtained from the I-V experiments as compared with the graphene transferred using the classical wet approach.
