Herein, a rational design of the photoanode is implemented to enhance H₂O₂ production by oxidizing H₂O in a portable photoelectrocatalysis (PEC) device. The obtained solution from this system is demonstrated for effective bactericidal activity against <i>Staphylococcus aureus</i> and <i>Escherichia coli</i>, while maintaining low toxicity toward hippocampal neuronal cells. The photoanode is achieved by Mo-doped BiVO₄ films, which are subsequently loaded with cobalt-porphyrin (Co-py) molecules as a co-catalyst. As a result, the optimal performance for H₂O₂ production rate was achieved at 8.4 μmol h⁻¹ cm⁻², which is 1.8 times that of the pristine BiVO₄ photoanode. Density functional theory (DFT) simulations reveal that the improved performance results from a 1.1 eV reduction in the energy of the rate-determining step of •OH adsorption by the optimal photoanode.

Harnessing of energy from ambient sources presents a significant opportunity to support sustainable development while mitigating environmental issues. Repurposing energy that would otherwise be wasted from high-consumption systems such as engines and industrial furnaces is essential for reducing ecological footprints and moving toward carbon-neutral goals. Furthermore, compact energy harvesting technologies will play a pivotal role in powering the rapidly expanding Internet of Things, enabling innovative advancements in smart homes, cities, industries, and health care that elevate our living standards. To achieve significant advancements in energy harvesting technologies, the development of innovative materials is crucial for converting ambient energy into electricity. In this regard, two-dimensional (2D) materials, a rising star in the material world, are profoundly and technologically intriguing for energy harvesting. The exceptional atomic thickness, high surface-to-volume ratio, flexibility, and tunable band gap effectively enhance their electronic, optical, and chemical properties, making them a potential candidate for use in flexible electronics and wearable energy harvesting technologies. Consequently, these unique properties of 2D materials remarkably enhance their energy harvesting capabilities, including photovoltaic, triboelectric, thermoelectric, and piezoelectric energy harvesting. Here, we present a tutorial-style review of 2D materials for harvesting energy from different ambient sources (aimed particularly at guiding and educating researchers, especially those new to the field), which starts with a brief overview of the promising properties of 2D materials for energy harvesting, then looks deeply into its advantages as compared to traditional materials along with their 3D counterparts, followed by providing insight into the mechanisms and performance of 2D material–based energy harvesters in portable/wearable electronics, and finally, based on current progress, an overview of the challenges along with corresponding strategies are identified and discussed.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 12","pages":""},"PeriodicalIF":24.2,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145831616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reach this goal, the development of new, breakthrough technologies is necessary and urgent. One such technology involves efficient carbon capture and its conversion into useful chemicals or fuels. However, achieving considerable amounts of efficiency in this field is a very challenging task. Even in natural photosynthesis occurring in plant leaves, the CO₂ conversion efficiency into hydrocarbons cannot exceed a value of 1%. Nevertheless, recently few reports show comparable higher efficiency in CO₂ to gaseous products such as carbon monoxide (CO), but it is hard to find selective liquid fuel products with a high value of solar to liquid fuel conversion efficiency. Herein, a NiFe-assisted hybrid composite dark cathode is employed for the selective production of solar-to-liquid fuels, in conjunction with a BiVO₄ photoanode. This process results in the generation of significant amounts of formaldehyde, ethanol, and methanol selectively. The primary objective of this study is to design and optimize a novel photoelectrochemical (PEC) system to produce solar-to-liquid fuels selectively.
