Special Issue Information

Dear Colleagues,

Industrial development is constantly improving, but the resulting problem of environmental pollution is serious. New pollutants such as industrial wastes, agricultural residues, and domestic pollutants have polluted the living environment and affected humans’ sustainable development. The main traditional pollution treatment methods are air separation and carbon adsorption. Since pollutants cannot be fully treated, developing new approaches to sustainable energy production to address climate change, water resource regulation, and industrial wastewater reduction represents an important research challenge.

This Special Issue intends to highlight recent progress and challenges in the advancement of catalytic nanomaterials for environmental protection and sustainable development. We welcome research on the design, synthesis, theory, structure, and characterization of various catalytic nanomaterials, including graphene, metal-based nanoparticles, transition metal dichalcogenides, and metal–organic frameworks (MOFs). Furthermore, their composites play an important role in achieving higher performance in the fields of environmental catalysis. Potential topics include, but are not limited to:

  • Nanocatalysts for soil/groundwater remediation.
  • Nanocatalysts for wastewater treatment.
  • Nanocatalysts for organic pollutant removal.
  • Coupled techniques for environmental remediation mediated by nanocatalysts.

In this study, we report the influence of the Pt concentration in CoxPt100−x alloys on the catalytic activity of the alloys for 4-nitrophenol (4-NP) reduction. More precisely, a series of CoxPt100−x alloys with a Pt concentration ranging between 60% and 95% were prepared using electrodeposition at controlled potentials from stable hexachloroplatinate aqueous solution. The Pt concentration was tuned by varying the electrodeposition potential from −0.6 to −0.9 V. The changes in the CoxPt100−x alloy microstructure and crystalline structure have been investigated using SEM and TEM analysis. Our results show that the microstructure and the crystalline structure of the as-prepared materials do not depend on the electrodeposition potential. However, the catalytic activity of CoxPt100−x alloys is closely correlated with the potential applied during electrochemical synthesis, hence the Pt content. We demonstrated that the synthesized materials present a high catalytic activity (approx. 90%) after six cycles of reusability despite the fact that the Pt content of the as-prepared alloys decreases. The easy preparation method that guarantees more than 97% catalytic activity of the CoxPt100−x alloys, the easy recovery from solution, and the possibility of reusing the CoxPt100−x alloys are the benefits of the present study.
