Special Issue Information

Dear Colleagues,

Nanomaterials have emerged as a promising class of materials for sustainable energy harvesting, owing to their unique structural characteristics, e.g., high specific surface area, quantum confinement effects and tunable electronic/optical properties, key advantages that address the limitations of traditional energy harvesting technologies, e.g., low solar/waste energy utilization, high fabrication cost, poor long-term stability in energy supply and carbon neutrality efforts. The strategic modulation of nanomaterials, e.g., 2D MXenes, Bi-based catalysts, perovskites and piezoelectric nanomaterials further optimizes their energy harvesting performance: such modulation not only enhances energy capture efficiency, e.g., broad-spectrum light absorption for photovoltaics and sensitive mechanical response for piezoelectric devices, but also acts as an efficient energy loss suppressor, e.g., reducing charge carrier recombination in thermoelectrics and minimizing interface resistance in integrated systems, thereby boosting overall energy conversion kinetics.

This Special Issue focuses on the latest advancements in nanomaterial-based sustainable energy harvesting, encompassing innovative nanomaterial synthesis strategies (e.g., hydrothermal synthesis, atomic layer deposition), structural/electronic property regulation (e.g., heteroatom doping, heterojunction construction), and practical applications in energy conversion (e.g., solar-to-electricity conversion, waste heat recovery, ambient mechanical energy collection). It aims to consolidate cutting-edge research, bridge fundamental insights into engineering applications, and inspire new directions for developing high-performance, low-cost, and eco-friendly nanomaterial-based energy harvesting systems to tackle global energy shortage and environmental sustainability challenges.

The development of versatile photocatalysts is crucial for comprehensive solutions to the intertwined challenges of the energy crisis and environmental pollution. This study presents a novel Bi3TiNbO9/Bi2MoO6 (BTNO/BMO) heterojunction fabricated via a solvothermal method. Advanced characterization techniques verified the successful synthesis of the as-integrated BTNO/BMO heterostructure. The BTNO/BMO composite exhibited superior performance in multiple applications: efficient degradation of tetracycline reaching 90.2%, removal of gaseous nitric oxide (NO), and photocatalytic reduction of carbon dioxide (CO2) to carbon monoxide (CO) with a yield of 51.3 μmol·g−1. The constructed Type-II heterojunction demonstrated a remarkable ability to suppress charge recombination, thereby significantly enhancing the photocatalytic activity. This work highlights the dual-functional capability of the BTNO/BMO heterojunction for simultaneous environmental purification and fuel production, providing a promising material platform and a strategic design concept for sustainable technological development.
