“…The essence of photosynthesis in natural leaves lies in the process of carbon assimilation by the photosystem utilizing light energy. This process results in the synthesis of glucose from CO 2 and water, ultimately leading to the formation of starch stores 37 , 38 . In addition, water and carbon sequestration products share transport pathways.…”

Developing artificial leaves to address the environmental burden of CO2 is pivotal for advancing our Net Zero Future. In this study, we introduce EcoLeaf, an artificial leaf that closely mimics the characteristics of natural leaves. It harnesses visible light as its sole energy source and orchestrates the controlled expansion and contraction of stomata and the exchange of petiole materials to govern the rate of CO2 sequestration from the atmosphere. Furthermore, EcoLeaf has a cellulose composition and mechanical strength similar to those of natural leaves, allowing it to seamlessly integrate into the ecosystem during use and participate in natural degradation and nutrient cycling processes at the end of its life. We propose that the carbon sequestration pathway within EcoLeaf is adaptable and can serve as a versatile biomimetic platform for diverse biogenic carbon sequestration pathways in the future.

“…Zhao et al (2023) reported a peak value of around 325 mV for wastewater ORP in the MFC of sediment coupled with Vallisneria natans [65]. The monitored data of the pH of the substrate are shown in Figure 5c, where it can be seen that in the first days, the values decreased from 6.55 to slightly acid on day 8 (5.31), and then in the following days, a significant increase was observed reaching values of 7.66 on day 30, showing optimal pH values in this period (6)(7)(8)(9) for the development of biofilms by microorganisms [66]. During the oxidation process of the organic compounds in the anode chamber of the MFC in the first days of operation, the microorganisms, in addition to generating electrons, also release protons (H + ions) [67].…”

The growing global energy demand drives the need to develop new clean energy technologies. In this context, microbial fuel cells (MFC) are one of the emerging technologies with great potential for eco-friendly energy generation; however, the correct choice of electrode material is a significant limitation in the optimal configuration of MFCs. Therefore, this research evaluated the efficiency of activated carbon (AC) anode electrodes for bioenergy production in MFC using synthetic wastewater as a substrate. Peak values of voltage (1120 ± 0.050 mV), current (4.64 ± 0.040 mA), power density (208.14 ± 17.15 mW/cm2), and current density (5.03 A/cm2) were generated, and the Rint obtained was 214.52 ± 5.22 Ω. The substrate was operated at pH values from 5.31 to 7.66, maximum ORP values (858 mV) were reached, and turbidity was reduced to 25.11 NTU. The SEM-EDS (scanning electron microscopy–energy-dispersive X-ray spectroscopy) analyses allowed us to observe the morphology and composition of the AC electrodes, revealing a predominance of O, C, Si, Al, Fe, K, and Ca. It is concluded that the AC electrodes have the potential to produce bioenergy at a laboratory by means of MFC.
