ABSTRACT: Transformation of greenhouse gas (CO₂) into valuable chemicals and fuels is a promising route to address the global issues of climate change and the energy crisis. Metal halide perovskite catalysts have shown their potential in promoting CO₂ reduction reaction (CO₂RR), however, their low phase stability has limited their application perspective. Herein, we present a reduced graphene oxide (rGO) wrapped CsPbI₃ perovskite nanocrystal (NC) CO₂RR catalyst (CsPbI₃/rGO), demonstrating enhanced stability in the aqueous electrolyte. The CsPbI₃/rGO catalyst exhibited > 92% Faradaic efficiency toward formate production at a CO2RR current density of ~ 12.7 mA cm−2. Comprehensive characterizations revealed the superior performance of the CsPbI₃/rGO catalyst originated from the synergistic effects between the CsPbI₃ NCs and rGO, i.e., rGO stabilized the α-CsPbI₃ phase and tuned the charge distribution, thus lowered the energy barrier for the protonation process and the formation of *HCOO intermediate, which resulted in high CO₂RR selectivity toward formate. This work shows a promising strategy to rationally design robust metal halide perovskites for achieving efficient CO₂RR toward valuable fuels.]]> Wed 13 Sep 2023 15:22:05 AEST ]]> Differentiating the Impacts of Cu2O Initial Low- and High-Index Facets on Their Reconstruction and Catalytic Performance in Electrochemical CO2 Reduction Reaction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50320 Tue 18 Jul 2023 14:51:03 AEST ]]> Solar driven ammonia synthesis with Co-TiOₓ and Ag nanowires enhanced Cu₂ZnSnS₄ photocathodes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55003 Thu 28 Mar 2024 10:15:18 AEDT ]]> Photo-electrochemical oxidation herbicides removal in stormwater: Degradation mechanism and pathway investigation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50779 Sat 05 Aug 2023 10:55:18 AEST ]]> Engineering a Kesterite-Based Photocathode for Photoelectrochemical Ammonia Synthesis from NO<inf>x</inf> Reduction https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51158 Mon 29 Jan 2024 18:36:06 AEDT ]]> Improved carrier dynamics in nickel/urea-functionalized carbon nitride for ethanol photoreforming https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50576 Mon 29 Jan 2024 18:33:27 AEDT ]]> Engineering defects in TiO2 for the simultaneous production of hydrogen and organic products https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50871 Mon 29 Jan 2024 18:25:16 AEDT ]]> Photo-electrochemical oxidation flow system for stormwater herbicides removal: Operational conditions and energy consumption analysis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52714 90 % removal) for diuron even at extremely high initial pollutant concentrations (240 μg L−1), demonstrating its capacity to handle varying contaminant loads in stormwater. Energy consumption analysis revealed that flow rate as the primary factor influenced the specific energy consumption rate. Higher flow rate (e.g., 610 mL min−1) were preferable in flow reactor due to its well-balanced performance between removal and energy consumption. These findings confirm that the PECO flow system offers an efficient and promising approach for stormwater treatment applications.]]> Mon 23 Oct 2023 16:12:30 AEDT ]]> Enhancing prediction accuracy of physical band gaps in semiconductor materials https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53200 Fri 17 Nov 2023 12:04:28 AEDT ]]> Predicting the rates of photocatalytic hydrogen evolution over cocatalyst-deposited TiO2 using machine learning with active photon flux as a unifying feature https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54861 Fri 15 Mar 2024 17:14:38 AEDT ]]>
