Selective inhibition of photosynthesis is a fundamental strategy to solve the global challenge caused by harmful cyanobacterial blooms. However, there is a lack of specificity of the currently used cyanocides, because most of them act on cyanobacteria by generating nontargeted oxidative stress. Here, for the first time, we find that the simplest β-diketone, acetylacetone, is a promising specific cyanocide, which acts on Microcystis aeruginosa through targeted binding on bound iron species in the photosynthetic electron transport chain, rather than by oxidizing the components of the photosynthetic apparatus. The targeted binding approach outperforms the general oxidation mechanism in terms of specificity and eco-safety. Given the essential role of photosynthesis in both natural and artificial systems, this finding not only provides a unique solution for the selective control of cyanobacteria but also sheds new light on the ways to modulate photosynthesis.

“…Inspired by this, researchers have proposed the approach of artificial photosynthesis to achieve the ultimate goal of solar energy utilization (i.e., to realize solar-to-chemical energy conversion and storage). [6,7] The fundamental principle of the artificial photosynthesis process is illustrated in Figure 1A. Typically, photogenerated electronhole pairs can be generated in semiconductor materials under photoexcitation.…”

2D materials show many particular properties, such as high surface‐to‐volume ratio, high anisotropic degree, and adjustable chemical functionality. These unique properties in 2D materials have sparked immense interest due to their applications in photocatalytic systems, resulting in significantly enhanced light capture, charge‐transfer kinetics, and surface reaction. Herein, the research progress in 2D photocatalysts based on varied compositions and functions, followed by specific surface modification strategies, is introduced. Fundamental principles focusing on light harvesting, charge separation, and molecular adsorption/activation in the 2D‐material‐based photocatalytic system are systemically explored. The examples described here detail the use of 2D materials in various photocatalytic energy‐conversion systems, including water splitting, carbon dioxide reduction, nitrogen fixation, hydrogen peroxide production, and organic synthesis. Finally, by elaborating the challenges and possible solutions for developing these 2D materials, the review is expected to provide some inspiration for the future research of 2D materials used on efficient photocatalytic energy conversions.

After long‐term evolution, organisms in nature have achieved optimal structure, organization, and function to adapt to the environment. Some ingenious biological structures have highly efficient solar light absorption, matter transmission, and natural photocatalytic properties, such as leaves, sunflowers, seaweeds, algae, bacteria. Artificial photocatalysis, which involves CO2 reduction and water splitting to obtain green renewable energy or oxygen, is of great significance for solving the problem of energy shortages, achieving carbon neutrality, and building a sustainable society. In order to improve the efficiency of artificial photocatalysis, it is necessary to develop highly efficient photocatalysts by expanding ideas and drawing innovative inspiration from nature. Artificially constructed photocatalysts with bionic structures achieved by simulating natural organisms have gradually become an exciting research field with great potential in recent years. This article reviews bioinspired photocatalysts and photocatalytic systems from the aspects of principle, composition, construction method, and the achieved performance. It is expected that this review will help researchers develop a systematic and in‐depth understanding for the biomimetic design of photocatalysts and photocatalytic systems.
