Phase‐Engineered MoS2 Quantum Monolayer Catalysts

Advanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

Fabrication of Ag3PO4/g-C3N4 heterojunction photocatalyst via in-situ growth and its photocatalytic performance.

PLoS ONE
Current methods for fabricating heterojunction photocatalysts often involve complex processes and weak interfacial bonding. To address the limitations of complex processes and weak interfacial bonding in existing heterojunction photocatalyst fabrication,

Self-repairing interphase reconstructed in each cycle for highly reversible aqueous zinc batteries

Nature Communications, 2022
Metallic zinc is an ideal anode material for aqueous rechargeable batteries but reversibility is a challenge. Here, the authors realise a dynamic real-time reconstructed interphase on zinc anode formed by graphitic carbon nitride quantum dot as an ...

X-ray diffractograms for titanium dioxide, graphitic carbon nitride, and their composites

X-ray diffractometry (XRD) spectra for titanium dioxide (TiO2), graphitic carbon nitride (g-C3N4), and their composites annealed at 200 and 300 oC. Bulk graphitic carbon nitride was prepared by polymerizing pure urea at 600 oC.

Ionic Cocrystal Programming of Spatial Ionic Organization in Carbon Nitrides Enables Highly Efficient H2O2 Photosynthesis

Advanced Materials, EarlyView.
Ionic cocrystal‐programmed ionic organization establishes a general strategy for electrostatic programming in polymeric photocatalysts. ABSTRACT Controlling the spatial organization of ions in polymeric photocatalysts remains a fundamental challenge for optimizing charge transport and catalytic selectivity in solar‐driven hydrogen peroxide (H2O2 ...

Pulsed Oxidative–Reductive Electrolysis Over Dual Cu and Co Single‐Atom Sites for Urea Electrosynthesis

Advanced Materials, EarlyView.
Alternating oxidative–reductive pulses synchronize CO2‐derived *CO and NH3‐derived *NHx intermediates over dual Cu and Co single‐atom sites, enabling urea and ethyl urea formation with a total C─N Faradaic efficiency of 42 ± 4%. In situ spectroscopy and theoretical calculations elucidate complementary Cu and Co functions, while oxidative controls ...
