| Abstract: A green composite film (RCewp/rGO) made from regenerated waste paper cellulose (RCewp) and reduced graphene oxide (rGO) was designed and used as an active material. The film produced from recycled paper demonstrated a stable maximum peak current of 10 μA over a 7 000 s cycle, with a maximum output power of 2.34 μW·cm-2 at a 100 Ω load. Additionally, the research highlighted the significant impact of metallic current collectors on moisture electricity generation. Notably, stainless steel collectors can produce an open-circuit voltage of up to 53 mV at 70% relative humidity (RH), as the redox reactions at the collector enhance current and voltage output under humid conditions. Furthermore, this moisture electricity generation film exhibited excellent performance when combined with magnesium-air batteries: at a 50% of RH, the RCewp/rGO electrode could generate an open-circuit voltage (Voc) of up to 1.37 V and a short-circuit current density of 0.132 mA·cm-2. When the RH increased to 90%, the Voc further rose to 1.57 V, with a short-circuit current density of 64.2 mA·cm-2. In contrast, the Mg-filter paper-Ni electrode, which was not connected to the moisture electricity generation film, only produced an output power and short-circuit current of 3.76×10-4 mW and 0.306 μA·cm-2, respectively. |
