Innovations and development of sustainable personal protective equipment: a path to a greener future

ENVIRONMENTAL SYSTEMS RESEARCH, Journal Year: 2024, Volume and Issue: 13(1)

Published: June 18, 2024

Abstract The unprecedented surge in the demand for personal protective equipment (PPE) worldwide during covid pandemic resulted a significant increase PPE consumption and subsequent waste generation. Despite importance of PPE, its widespread usage disposal have sparked worries about environmental impact long-term sustainability. increasing awareness challenges, resource scarcity, urgent need to mitigate climate change necessitates paradigm shift product design, manufacturing process, management PPE. To address these challenges sustainable future, development degradable polymers natural fibers offers promising alternative traditional plastics. Additionally, recycling upcycling methods can convert into valuable alternate products or energy sources, thereby reducing their impact. Better systems, comprehensive policy frameworks, international collaborations are essential effective promotion practices. collaborative efforts across governments, manufacturers, research institutions, authorities crucial transitioning more industry circular economy, ultimately benefiting both environment society.

A [Cu₂O₂]²⁺ Core in Cu/ZSM-5 for Efficient Selective Catalytic Oxidation of Nitrogen-Containing VOCs and NH₃

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(5), P. 1016 - 1027

Published: Feb. 5, 2024

Highly efficient elimination of nitrogen-containing volatile organic compounds (NVOCs) or NH3 via selective catalytic oxidation (SCO) while avoiding NOx is a strongly desired process for their control. However, limited by lack fundamental guidance such as accurate active site and reaction mechanisms, the targeted design high-performance catalysts faces severe challenges. Herein, ZSM-5 zeolites supported different copper species were used in SCO dimethylformamide (DMF) NH3. Optimal 8% Cu/ZSM-5 had highest N2 selectivity above 94%. Various situ spectroscopic characterizations DFT theoretical calculations precisely identified that μ-(η2:η2)-peroxo dicopper (bent; [Cu2O2]2+) core, which associated with two Al sites separated three SiO4 tetrahedra units 10-membered ring ZSM-5. The dynamic behavior DMF-SCO was revealed to be [Cu2O2]2+ transformed into mono-(μ-oxo) upon DMF adsorption, opposite occurred when O2 attacked. In DRIFTS elucidated pathway indicated disassociating N–H bond rate-determining step transforming N2. This work not only points way NVOCs but provides methodological implications study structures.
