A mesh-like BiOBr/Bi₂S₃ nanoarray heterojunction with hierarchical pores and oxygen vacancies for broadband CO₂ photoreduction

Abstract

Exploring highly efficient heterostructured photocatalysts for converting CO2 to value-added chemicals has long been pursued, which is mainly limited by inefficient visible/near-infrared (NIR) photon capture, undesirable electron-hole recombination, and insufficient...

Spatially Separated Redox Cocatalysts on Ferroelectric Nanoplates for Improved Piezophotocatalytic CO2 Reduction and H2O Oxidation

“…To avoid the interference originating from the decomposition of possible organic impurities in the catalysts and reactors, control experiments are performed and no CO is detected when the reaction is carried out in an Ar atmosphere, in the absence of a catalyst, and without ultrasonic vibration or light illumination. Moreover, a 13 C isotopic labeling experiment is employed to identify the carbon source of CO. As displayed in Figure S8a, the mass signal of 13 CO (m/z = 29) proves that the evolved CO indeed derives from the reduction of CO 2 . The reusability of AuCu/PbTiO 3 /MnO x in CO 2 reduction is investigated under simultaneous ultrasound and light.…”

Obviously, during five consecutive cycles, there is no obvious decline in the CO yield within 20 h (Figure S9).…”

Cu-BTC-confined synthesis of Cu-Cu2O-CuS nanojunctions embedded in a porous carbon matrix for remarkable photothermal CO2conversion

“…Similar to plasmonic Au, extra hot electrons are generated by plasmonic Cu and injected into Cu 2 O and CuS for the photocatalytic CO 2 reduction reaction despite this effect being very small. 55,56…”

Embedding Plasmonic Metal into Heterointerface of MOFs‐Encapsulated Semiconductor Hollow Architecture for Boosting CO2 Photoreduction

“…Under visible light irradiation, multiple characteristic peaks can be recorded, including monodentate carbonate (m-CO 3 (1310, 1668 and 1682 cm −1 ), COOH* (1147, 1507, and 1540 cm −1 ) and CO* (1179 cm −1 ), and the intensities of which are gradually improved with the accumulation of irradiation time. [49][50][51][52][53][54][55][56][57][58] According to the DRIFTS results, the possible CO 2 reduction pathway on H-CdS@ZIF-8 and H-CdS/Au@ZIF-8 can be proposed as follows * + → * CO CO…”
