Direct Z‐Scheme Hetero‐phase Junction of Black/Red Phosphorus for Photocatalytic Water Splitting

Abstract

Blackphosphorus (BP) has recently drawn attention in photocatalysis for its optical properties.However,limited by the rapid recombination of photogenerated carriers,the use of BP for photocatalytic water splitting still remains ah uge challenge.H erein, we prepare ab lack/red phosphorus (BP/ RP) hetero-phase junction photocatalyst by aw et-chemistry method to promote the interfacial charge separation and thus achieve Z-scheme photocatalytic water splitting without using sacrificial agents.The Z-scheme mechanism was confirmed by time-resolved transient absorption spectroscopy. This work provides an ovel insight into the interface design of heterophase junction with atomic precision.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Tracking S‐Scheme Charge Transfer Pathways in Mo2C/CdS H2‐Evolution Photocatalysts

“…According to the date from UPS, the work function ( Φ , difference between the Fermi and vacuum level) and E VBM (VB energy) can be calculated by previous report. [ 24 ] Figure 4C shows the UPS spectra of CdS and Mo 2 C. The ϕ s of CdS and Mo 2 C were calculated of −4.04 and −4.56 eV, indicating CdS and Mo 2 C should be a reduction‐type photocatalyst (with higher Fermi level and smaller work function) and an oxidation‐type photocatalyst (with lower Fermi level and larger work function), respectively. The VB energies ( E VB ) of CdS and Mo 2 C were calculated to be −5.74 and −6.18 eV (vs vacuum), respectively.…”

Cryo-induced closely bonded heterostructure for effective CO2 conversion: The case of ultrathin BP nanosheets/g-C3N4

“…In order to effectively catalyze CO 2 reduction, various photocatalysts had been investigated and developed [7][8][9] . In pre-vious works [10][11][12] , most of high-efficiency photocatalysts of CO 2 reduction contained metal elements, which were expensive and environmentally harmful.…”

Black phosphorus synthesized by solvothermal reaction from red phosphorus and its catalytic activity for water splitting

“…14 Liu et al reported that synthesis of composite of BP/RP with high photocatalytic activity for water splitting from RP in amine solvent. 15 However, there are few reports on method to get high yield of BP and the synthesis mechanism of BP from RP were unclear.…”
