The disposal of natural wastes has become a global problem and the use of lower-grade gums is very limited owing to their impurities as well as sticky nature. Rather than disposing these wastes, nanoporous carbon (nC) has instead been synthesized by carbonization and exfoliation. The synthesized nC exhibits a substantially high surface area along with abundant micro/mesopores. This desirable and useful nature of nC is well-suited for water-driven effective electrical energy conversion, which enables the fast evaporation of water via a capillary action through nanopores. Under asymmetric wetting in a water container and ambient conditions, the nC-based energy harvesters showed high capability of electricity production and reliable output generation, easily turning on a blue light-emitting diode (2.5 V and 20 mA) using a stored power source. In summary, many energy harvesters can be manufactured for the scale-up of electricity, and the suitability of regenerated carbon nanomaterials for green energy harvesting can contribute toward alleviating chronic environmental issues.

将非食品级树胶废料回收为纳米多孔碳，以实现可持续的能源收集
天然废物的处置已成为一个全球性问题，由于劣质口香糖的杂质和粘性，其使用非常有限。与其处理这些废物，不如通过碳化和剥离来合成纳米孔碳（nC）。合成的nC表现出相当高的表面积以及丰富的微孔/中孔。NC的该较佳的和有用的性质非常适用于水驱动的有效的电能量转换，从而使水的快速蒸发经由通过纳米孔的毛细作用。在水容器中的非对称润湿和环境条件下，基于nC的能量采集器显示出很高的发电能力和可靠的发电量，可以使用存储的电源轻松打开蓝色发光二极管（2.5 V和20 mA）。总而言之，可以制造许多能量收集器以扩大电力规模，而再生碳纳米材料对绿色能量收集的适用性可有助于缓解慢性环境问题。
