C≡N vacancy engineering of Prussian blue analogs for the advanced oxygen evolution reaction

Mechanistic insights into the electrolyte effects on the electrochemical nitrogen reduction reaction using copper hexacyanoferrate/f-MWCNT nano-composites

“…The presence of such defects in the PBAs has been reported to result in the modulation of the electronic structure, enhancement of charge transfer efficiency and suppression in the leaching of metal active sites in defect engineered PBAs. 37,57–59 Our above presented physicochemical characterization and electrochemical investigations clearly establish the increased number of defect sites in the CuFe PBA/f-CNT composite. This is well evident from the TGA, XPS, EIS and voltammetric investigations that were carried over the pristine and CuFe PBA/f-CNT composite in the present work.…”

Waste Iron Oxidation Reaction-Assisted Electrochemical Flocculation for Rhodamine B Extraction from Wastewater: A Hands-On Experiment for Undergraduates

“…Achieving global carbon neutrality can be effectively accomplished through the implementation of pollution reduction and carbon emission reduction strategies. − Wastewater from various industries poses a significant threat to the environment, ecology, and human living. − The detection and purification of water quality are particularly important . Generally, the nephelometer, colorimeter, and turbidity are used for water quality detection. − Traditional techniques of removing pollutants from wastewater via chemical oxidation can be energy-intensive and emit carbon, nitrogen, and sulfur species, making it urgent to find alternative methods that do not produce secondary pollution. − Flocculation is a highly effective technique for extracting dye molecules and heavy ions from wastewater through static adsorption, without oxidizing the pollutants into gaseous species. , Recent studies have explored the use of biocoagulants extracted from Moringa oleifera seeds for coagulation-flocculation processes to treat paint wastewater, achieving a significant reduction in turbidity with a yield of 99.9% under optimized conditions .…”

Ni–Co hexacyanoferrate hollow nanoprism with CN vacancy for electrocatalytic benzyl alcohol oxidation

“…12 The deliberate creation of cyanide (CN) vacancies within the PBAs matrix has been recognized as a successful strategy to amplify their catalytic effectiveness. 13,14 However, this enhancement often requires the allocation of additional energy and the application of sophisticated, costly equipment, which presents a barrier for scalable and economic applications. 15,16 Herein, we detail the fabrication of nickel cobalt hexacyanoferrate hollow nanoprisms (Ni x Co 1 -HCF HN) through a novel self-sacrificing template method executed in mild conditions without the need for elevated energy or complex machinery.…”
