Summary: A composite photoelectrode B-nGO/H:(NiO/TiO2) NTs with a unique heterostructure nanotube arrays was synthesized. The p-n junction created between p-type NiO and n-type TiO2 facilitates the electron-hole pair separation and interfacial electron transfer. The introduction of boron-doped reduced nanographene oxide nanoparticles (B-nGO NPs) and hydrogenation treatment further optimize the electron-hole separation and enhance the electron transfer. The as-synthesized B-nGO/H:(NiO/TiO2) NTs exhibit a high photocurrent density and an effective photoconversion efficiency under simulated sunlight irradiation.

Summary: A wet-incipient impregnation method was used to synthesize hierarchical porous bimetallic (Co, Zn)-zeolitic imidazolate frameworks (ZIF-8)/TiO2 for efficient photocatalytic water splitting. Co@ZIF-8/TiO2 exhibited significantly higher photocatalytic efficiency than TiO2, with a hydrogen generation rate of 13 mmol·h(-1)·g(-1) and a 151-fold increase in catalytic performance. The hierarchical porous structure of Co@ZIF-8 facilitated charge transfer and provided efficient transport channels. This study demonstrates the potential of hierarchical porous metal-organic frameworks (MOFs) as support and promoter in photocatalytic applications of TiO2.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
