NiFe layered double hydroxide as an efficient bifunctional catalyst for electrosynthesis of hydrogen peroxide and oxygen

High-efficiency oxygen reduction by late transition metal oxides to produce H2O2

“…6,7 Moreover, hydrogen peroxide can be stored in small portable containers due to its low dosage and reduced corrosiveness in diluted form, making it convenient and safe. 8 Worldwide, hydrogen peroxide sales are progressively rising. A report by Global Market Insight projects that by 2025, the global market for hydrogen peroxide will be worth 3.68 billion US dollars.…”

Trace Mn decorating nitrogen-doped carbon electrocatalysts for self-powered bio-electro-fenton cells toward simulated wastewater treatment

“…[1][2][3] However, the current method of producing H 2 O 2 , known as the anthraquinone method, is plagued by high energy consumption and severe pollution, despite its ability to achieve large-scale production. [4][5][6][7] Consequently, it is essential to explore a safe, cost-effective, and efficient "green" H 2 O 2 production method. There are several methods available for synthesizing H 2 O 2 , including water oxidation reaction (WOR), direct synthesis from a mixture of hydrogen and oxygen, and the electrochemical 2electron (2e − ) oxygen reduction reaction (ORR).…”

Enhancing Electrocatalytic Water Oxidation of NiFe-LDH Nanosheets via Bismuth-Induced Electronic Structure Engineering

“…Currently, transition-metal (Fe, Co, and Ni)-based catalysts exhibit electrocatalytic activity comparable to that of noble metals in water splitting and are the most promising candidates for electrocatalytic water splitting. 11,12 Especially, layered double hydroxides (LDHs) formed from transition metals exhibit excellent OER and overall water splitting performance under alkaline conditions. 13,14 Generally, LDHs exhibit twodimensional (2D) layered nanosheets.…”

“…Currently, transition-metal (Fe, Co, and Ni)-based catalysts exhibit electrocatalytic activity comparable to that of noble metals in water splitting and are the most promising candidates for electrocatalytic water splitting. , Especially, layered double hydroxides (LDHs) formed from transition metals exhibit excellent OER and overall water splitting performance under alkaline conditions. , Generally, LDHs exhibit two-dimensional (2D) layered nanosheets. This unique 2D layered structure gives LDH many advantages, such as flexible tunable metal cations in the host layer, easy regulation of interlayer anions and distances, and tunable nanosheet thickness. − However, the relatively inferior conductivity of LDHs is often disadvantageous for electron transportation, which eventually influences the electrocatalytic performance .…”
