Solar‐driven interfacial evaporation systems have been considered to achieve broad application prospects in the field of cogeneration of steam and electricity. However, the electricity generated is often independent of the photothermal system, hindering their integration. Compared with traditional materials such as metals and semiconductors, the application of biomass materials can solve the problems of high cost and environmental pollution in the expansion and relevance of interfacial evaporation technology. Herein, the solar evaporator composed of carbonized sphagnum palustre with cellulose fabric (CSPF) is fabricated for simultaneous steam production and power generation. Additionally, a device consisting of the CSPF and other accessories such as heating wires is designed to enhance steam production by self‐driven electrothermal heating. The self‐driven solar evaporator endows enhanced evaporation rates to 2.12 kg m−2 h−1 under electrothermal effect and the high electrical energy outputs of 520 mV. The solar evaporator has good salt tolerance and excellent cycle stability, maintaining a high evaporation rate in high‐salt solutions and after 24 cycles of testing. The outdoor evaporation tests reveal the encouraging performance of the steam and energy generators in real environment. Such superior performance of comprehensive device has great potential for integrated and sustainable application in cogeneration systems.

Recent Progress Using Solid-State Materials for Hydrogen Storage: A Short Review

et al. 2022

With the rapid growth in demand for effective and renewable energy, the hydrogen era has begun. To meet commercial requirements, efficient hydrogen storage techniques are required. So far, four techniques have been suggested for hydrogen storage: compressed storage, hydrogen liquefaction, chemical absorption, and physical adsorption. Currently, high-pressure compressed tanks are used in the industry; however, certain limitations such as high costs, safety concerns, undesirable amounts of occupied space, and low storage capacities are still challenges. Physical hydrogen adsorption is one of the most promising techniques; it uses porous adsorbents, which have material benefits such as low costs, high storage densities, and fast charging–discharging kinetics. During adsorption on material surfaces, hydrogen molecules weakly adsorb at the surface of adsorbents via long-range dispersion forces. The largest challenge in the hydrogen era is the development of progressive materials for efficient hydrogen storage. In designing efficient adsorbents, understanding interfacial interactions between hydrogen molecules and porous material surfaces is important. In this review, we briefly summarize a hydrogen storage technique based on US DOE classifications and examine hydrogen storage targets for feasible commercialization. We also address recent trends in the development of hydrogen storage materials. Lastly, we propose spillover mechanisms for efficient hydrogen storage using solid-state adsorbents.

“…A new trend in carbonaceous sorbents is the preparation of porous carbon materials from biomass pyrolysis. It has been shown that the pyrolysis temperature, pyrolysis heating rate, and carbon-containing precursors strongly affect the yield and structure of the resulting porous carbons . Another attempt is to fabricate highly porous carbon sorbents by carbonizing highly crystalline metal–organic frameworks (MOFs) without any carbon precursors …”
