Utilizing Molybdenum to Tailor the Electronic Structure of Iron Through Electron Complementary Effect for Promoting Oxygen Reduction Activity

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 16, 2025

Abstract Tailoring the electronic structure of later transition metal‐based electrocatalysts by incorporating early metal based on complementary effect is anticipated to enhance electrocatalytic activity. Herein, modulation Fe 3 C through utilization Mo 2 promote oxygen reduction reaction (ORR) activity reported. In situ characterizations combined with theoretical calculations reveal that electron‐donating capability molybdenum in active center iron optimizes adsorption and activation oxygen. Concurrently, d‐band much closer Fermi level, which reduces energy barrier for rate‐determining step ( * OOH → O), thereby enhancing ORR alkaline media, catalyst delivers a half‐wave potential E 1/2 ) 0.89 V maintains its efficiency mere 8 mV decay after 10 000 cycles, surpassing Pt/C. Moreover, it can serve as an air cathode both liquid‐state all‐solid‐state zinc‐air batteries (ZABs) shows promising applications portable devices. This work brings innovative design concept highly efficient suitable advanced

Modification of Saccharomyces cerevisiae Cells with Metal Hexacyanoferrates for the Construction of a Yeast-Based Fuel Cell

Molecules, Journal Year: 2025, Volume and Issue: 30(1), P. 137 - 137

Published: Jan. 1, 2025

This research presents a simple procedure for chemically modifying yeast (Saccharomyces cerevisiae) cells with nickel hexacyanoferrate (NiHCF) and ferric hexacyanoferrate, also known as Prussian blue (PB), to increase the conductivity of cell wall. Using linear sweep voltammetry, NiHCF-modified PB-modified (NiHCF/yeast PB/yeast, respectively) were found have better wall in [Fe(CN)6]3− glucose-containing phosphate-buffered solution than unmodified yeast. Spectrophotometric analysis showed that modification NiHCF had less harmful effect on viability PB. The use NiHCF/yeast PB/yeast construction yeast-based fuel allowed maximum power densities 62.66 mW/m2 94.09 be achieved. These values much higher those obtained using (42.25 mW/m2). renewed by replenishing suspension anolyte or FeCl3 salt catholyte. 77.4% 50.1% initial density
