Abstract

Green renewable technologies have become a focus of energy research due to the adverse impacts of fossil fuels, greenhouse gases, climate change, global warming, and battery short life. A new generation of biomaterials with spontaneous piezoelectric properties is highly emerging for generating electricity from ubiquitous mechanical energy. Recent years, there has been a concerted effort to engineer robust 1D functional materials for nanogenerators, leveraging cellulose as the foundational material. This research work produced nanofiber composite of zinc oxide (ZnO) nanoparticles and MXene (Ti₃C₂) nanosheets incorporated into cellulose acetate (CA) polymer through electrospinning process forms the basis for ecofriendly highly durable smart textile fabrication. Formation of MXene nanosheets heterostructures significantly promoted the low conversion efficiency of conventional ZnO to highest output voltage of ⁓35 V, and a short circuit current of ⁓3.34 µA. Synergistic contribution of the piezo-enhanced photocatalytic activity of MXene/ZnO hetero-structured smart nanofibers offers greater environmental remediation of water resources from the contamination of methyl orange (MO) dye with a rate constant (k) of 66.14×10⁻³ min⁻¹. In addition, intelligent dual mechanistic membranes support sustainable operations (20000 cycles) with strong morphological and performance retention (⁓92 %), showing good chemical and mechanical stability even under harsh operating conditions.

用于环境修复的自供电可持续智能纺织品中尺寸受限的 MXene 纳米片的协同效应

由于化石燃料、温室气体、气候变化、全球变暖和电池寿命短等不利影响，绿色可再生技术已成为能源研究的重点。新一代具有自发压电特性的生物材料正在崭露头角，可利用无处不在的机械能发电。近年来，人们一直致力于利用纤维素作为基础材料，为纳米发电机设计坚固的一维功能材料。这项研究工作通过电纺丝工艺将氧化锌（ZnO）纳米颗粒和 MXene（Ti3C2）纳米片材与醋酸纤维素（CA）聚合物结合在一起，制成了纳米纤维复合材料，为制造生态友好、高度耐用的智能纺织品奠定了基础。MXene 纳米片异质结构的形成大大提高了传统 ZnO 的低转换效率，使最高输出电压达到⁓35 V，短路电流达到⁓3.34 µA。MXene/ZnO 异质结构智能纳米纤维的压强增强光催化活性具有协同作用，能以 66.14×10-3 min-1 的速率常数（k）更有效地修复水资源，使其免受甲基橙（MO）染料的污染。此外，智能双机械膜支持可持续运行（20000 次循环），形态和性能保持率高（⁓92%），即使在恶劣的运行条件下也能表现出良好的化学和机械稳定性。
