Recent progress in bismuth oxyhalides-based heterojunctions for CO2 photoreduction

Green aspects of photocatalysts during corona pandemic: a promising role for the deactivation of COVID-19 virus

“…5a and b) and photocatalytic activeness of the coatings, vast research efforts have been put forward to exploit the self-cleaning properties of nanomaterials via photo-activation, which can be substantially benecial for commercial and the medical sector. [95][96][97] The surface coating of both Cu and CuO nanoparticles (Fig. 2) has been shown to possess considerable antimicrobial activity even against SARS-CoV-2 aer 4 h of exposure to plastics and stainless steel, where the virus can live up to 72 h. Inspired by this, Kumar et al reported a smart and facile technique to construct an antiviral mask by a coating a non-woven surgical mask with shellac/ copper (Cu and CuO) nanoparticles to enhance the hydrophobicity of the mask's surface and make it resistant to aqueous droplets (Fig.…”

Current perspective in metal oxide based photocatalysts for virus disinfection: A review

“…These generated reactive oxygen species (ROS; •OH, H 2 O 2 , H + , and •O 2 − ) during photocatalysis having redox potential participates in photocatalytic disinfection and degradation processes ( Soni et al, 2021c ; Kumar et al, 2021a ). The photocatalytic performance mainly depends upon the type of potential photocatalyst used, their physical and chemical properties, and the light source ( Kumar et al, 2021a , 2021b ; Raizada et al, 2020 ).…”
