As a spontaneous renewable energy-based technology, with an astonishing ability to destroy recalcitrant organic pollutants under ambient conditions, solar-driven heterogeneous photocatalysis has sparked immense interest over the past decade. However, creating photocatalysts astounding visible-light harnessing capacity and undemanding recuperation persists as significant hurdle widespread exploitation of in water treatment. Herein, we propose potentially nontoxic, robust, durable, self-supporting photocatalyst, based on situ growth few-layer (FL) WS2 nanosheets interpenetrating channels nitrogen (N)-doped graphene aerogel (henceforth denoted "WNGA"). Constructed through mild hydrothermal processing scheme, WNGA shows self-floating capability, exceptional mechanical resilience, remarkable solar absorption visible range. In addition, coexistence pyridinic N species FL-WS2 clusters synergistically provides surplus active sites for catalytic reactions. Besides, interconnected conductive networks coherently upregulate charge separation transfer 3D. result these beneficial attributes, presents prominent photocatalytic activity excellent recycling stability. For instance, combination adsorption partial oxidation, can dissociate up 93% caffeine, most widely consumed psychoactive substance, into innocuous products multiple cycles. figure-of-merit commercial potential WNGA, also demonstrate degradation caffeine four different real matrixes, viz., tap water, pond municipal wastewater, hospital wastewater. The properties, improved durability, facile retrieval opportunities validate application eliminate substances aqueous environments.

Microbial corrosion of CoCrMnNi high entropy alloy by Pseudomonas aeruginosa through electron transfer between Mn and microbe

Journal of Materials Research and Technology, Год журнала: 2024, Номер 29, С. 386 - 399

Опубликована: Янв. 17, 2024

The microbiologically influenced corrosion of CoCrMnNi high entropy alloy induced by P. aeruginosa was investigated in this work. results electrochemical tests, time-of-flight secondary ion mass spectrometry and X-ray photoelectron spectroscopy showed that the thickness passive film significantly decreased presence HEA accelerated. When organic nutrients were deficient, extracellular electron transfer process promoted resistance further according to potentiodynamic polarization Mott-Schottky. effect deficiency on MIC acceleration more prominent after degradation film. Mn metal substrate preferentially participated bacterial metabolism as an alternative energy source due activity.
