A versatile, eco-friendly synthesis scheme was developed to fabricate a series of hierarchically-structured CuBi2O4 composites for environmental applications. By simple tuning of the synthesis protocol (i.e. controlling the ethylene glycol to water ratio in the reaction matrix and employing different auxiliary metal precursors consisting of Cu(2+), Co(2+) or Fe(3+) species), deposition of vario...

A p-type heterojunction photoelectrode consisting of platinized CuBi2O4 layered on a CuO film was prepared. The CuO|CuBi2O4|Pt electrode photo-generates H2 in pH neutral aqueous solution during visible light irradiation and exhibits a substantially enhanced photocurrent compared to CuO|Pt and CuBi2O4|Pt electrodes. Reduced electron-hole recombination by the band offsets in the heterostructure i...

In this research work, a copper bismuth oxide- (CuBi2O4-) based thin-film solar cell has been proposed for the lead and toxic-free (Al/ITO/TiO2/CuBi2O4/Mo) structure simulated in SCAPS-1D software. The main aim of work to make an ecofriendly highly efficient cell. absorber layer CuBi2O4, buffer TiO2, electron transport (ETL) ITO have used simulation. performance suggested photovoltaic devices w...

A new dispenser and scanner system is used to create and screen Bi-M-Cu oxide arrays for cathodic photoactivity, where M represents 1 of 22 different transition and post-transition metals. Over 3000 unique Bi : M : Cu atomic ratios are screened. Of the 22 metals tested, 10 show a M-Cu oxide with higher photoactivity than CuO and 10 show a Bi-M-Cu oxide with higher photoactivity than CuBi2O4. Cd...

Photoelectrochemical Water Splitting A simple substitution of Ag+-ions into the CuBi2O4 lattice causes increased hole-concentration, as demonstrated in article 2300085 by D. Amaranatha Reddy, Tae Kyu Kim, and co-workes. Introducing NiO a hole selective layer beneath Ag-CuBi2O4 porous film facilitates efficient charge separation transfer at interface leading to enhanced photoelectrochemical perf...

Dye sensitized solar cell was assembled using TiO2 nanoparticle with argon-nitrogen plasma treatment and CuBi2O4 sputtering electrode prepared by plasma irradiation. The electric property of the solar cell fabricated by plasma treated TiO2 nanoparticle was improved because the physical and chemical property of TiO2 particles affected from the nitrogen plasma treatment

Semiconductor catalysts play a potential role for efficient electrocatalytic hydrogen production. In this work, copper bismuth oxide (CuBi2O4) nanostructures were synthesized via the coprecipitation method using two different Cu precursors: one is Cu(NO3)3·9H2O and other CuCl2. When Cu(NO3)3·9H2O, sample showed an interconnected aggregated irregular spherical CuBi2O4 nanoparticle structure. On ...

A novel CuBi2O4 consisting of self-assembled spherical nanocolumn arrays (CuB-H) was synthesized via a facile hydrothermal method. It was further modified by controlling the Cu:Bi ratio during synthesis to become an efficient bi-functional catalyst (CuB-2.5) activate persulfate (PS) and peroxymonosulfate (PMS) for 1H-benzotriazole (BTZ) removal. Characterization of CuB-2.5 using XRD, 10 FESEM, ...

As interest in hydrogen energy grows, eco-friendly methods of producing are being explored. CuBi2O4 is one the p-type semiconductor cathode materials that can be used for photoelectrochemical production via environment-friendly water electrolysis. has a bandgap 1.5 – 1.8 eV which allows it to photogenerate electrons and holes from absorption visible light. This study investigated effect sulfur ...
