A hybrid zeolitic imidazolate framework-derived ZnO/ZnMoO₄heterostructure for electrochemical hydrogen production

Abstract

Sustainable hydrogen fuel supply through electrochemical water splitting requires high-efficient, low-cost and robust electrocatalysts. Interface engineering is of key importance to improve the catalytic performance in the heterogeneous electrocatalysis system....

Ni3N/Co4N nanosheet heterojunction electrocatalyst for hydrogen evolution reaction in alkaline fresh water/simulated seawater

“…40 The EIS spectrum obtained can be used to study the surface phenomena of the catalytic electrode, which is another important means to reveal the activity of the catalyst. 41 In Fig. 4d, the EIS spectra of Ni 3 N/Co 4 N exhibit the smallest semicircle compared to Co 4 N and Ni 3 N, which reflects the smallest charge transfer resistance ( R ct ) for the Ni 3 N/Co 4 N electrode.…”

Tuning Electrochemical Hydrogen-Evolution Activity of CoMoO4 through Zn Incorporation

“…From the results it can be concluded that Zn incorporation modified the HER electrocatalysis, explaining that all Zn-substituted materials have better activity compared to their unsubstituted counterpart. To compare the results obtained in this work, the HER performances of previous studies have been tabulated in Table S3 [18,20,[49][50][51][52][53][54][55].…”

Charge Transfer-Regulated Bimetallic ZnCd-ZIF-8/Graphene Oxide Hybrid Nanostructures for Solar Hydrogen Generation

“…6 Despite the material's potential for water splitting, its performance was restricted by the inadequacy of UV irradiation, which only accounts for 4% of the solar spectrum, while visible light makes up approximately 46%. 7 Researchers are increasingly focusing their efforts on developing novel photocatalysts that can exploit visible or near-infrared light to achieve high photocatalytic activity. 8 The bandgap of photocatalysts is a critical factor for successful photocatalytic water splitting, as it must be suitable for both the reduction and oxidation potentials of water, which are +0.00 and +1.23 V versus the normal hydrogen electrode (NHE).…”

“…Traditional photocatalysts exhibit poor performance due to the combined effect of low quantum yield and wide distribution of photoinduced carriers, which results in limited light response at larger wavelength regions and diminished photocatalytic activity . Despite the material’s potential for water splitting, its performance was restricted by the inadequacy of UV irradiation, which only accounts for 4% of the solar spectrum, while visible light makes up approximately 46% . Researchers are increasingly focusing their efforts on developing novel photocatalysts that can exploit visible or near-infrared light to achieve high photocatalytic activity .…”
