Membraneless, self-powered immunosensing of a cardiac biomarker by exploiting a PEC platform based on CaBi2Ta2O9 combined with bismuth oxyiodides

“…S2. † The sample exhibited the XRD peaks of tetragonal CuBi 2 O 4 (ICSD, 67 018), SnO 2 (ICSD, 16 635) from the FTO substrate, [38][39][40] and some minor peaks attributed to Bi 2 O 3 . Fig.…”

Plasmonic Au nanoparticle sandwiched CuBi2O4/Sb2S3photocathode with multi-mediated electron transfer for efficient solar water splitting

“…Despite the great advantages of CuBi 2 O 4 as a photocathodic absorber material, relatively very few studies have been reported. 12–15 The theoretical photocurrent density reported for CuBi 2 O 4 under AM 1.5 G is 19.5–24.5 mA cm −2 , but in practical applications, this value is way too low compared to the theoretical value. 16 The practical photocurrent densities of CuBi 2 O 4 photocathodes are lower due to their poor charge transport, lower absorption coefficient, higher charge recombination rates, and poor stability towards photo-corrosion, which limit their PEC performance.…”

CuInS2 Nanosheet Arrays with a MoS2 Heterojunction as a Photocathode for PEC Water Splitting

“…34 Sellappan and Varunkumar fabricated the CuBi 2 O 4 /MoS 2 photocathode delivered a high photocurrent value of −0.182 mA/cm 2 than pristine CuBi 2 O 4 (−0.082 mA/ cm 2 at 0.6 V vs RHE) owing to the presence of MoS 2 . 35 Recently, Dolai et al developed a MoS 2 @CdS heterojunction photocathode with a photocurrent density of −6.45 mA/cm 2 at −0.5 V vs RHE. This improvement was attributed to the presence of MoS 2 , which improved the photostability, charge carrier separation, and transport.…”
