It unfolded good CO2 reduction reaction (CO2RR) performance under photoelectrocatalytic (PEC) conditions, achieving a 25% higher catalytic efficiency than PP. This photocatalyst enabled urea (CO(NH2)2) synthesis from CO2 and NO2− while co-producing NH3, HCOOH, and CO. It exhibited broad pH tolerance (pH 4–10). Infrared data revealed that NO2− and CO2 adsorbed on the catalyst surface, formed *NO2 and *OCO intermediates, respectively. Sequential hydrogenation and dehydration steps yielded *NH and *CO, which coupled in situ to form CO(NH2)2.

However, the performance is severely limited by low carrier mobility, short hole diffusion length, and slow oxygen evolution reaction kinetics. In this review, we discuss recent advancements of hematite photoanodes by promoting water oxidation reaction on the surface, enhancing charge separation and transport in the bulk, and paralleling multi-stacked photoelectrodes. The surface reaction kinetics of hematite photoanodes could be improved by surface hole storage layer, surface-loaded cocatalyst, and surface post-treatment. The charge separation and transport in the bulk could be enhanced by dual element doping and heterojunction/homojunction constructing. In particular, an innovative parallel multi-stacked hematite photoanodes has made a significant breakthrough of photocurrent density, achieving the approximate theoretical value of 10 mA cm<small><sup>‒2</sup></small> at 1.23 V<small><sub>RHE</sub></small> under 100 mW cm<small><sup>‒2</sup></small> solar irradiation.
