Abstract Metal–organic frameworks (MOFs) exhibit large surface areas and low thermal conductivity, making them promising for thermoelectric generation. However, their limited electrical conductivity poses a significant hurdle to be practically useful. Traditionally, enhancing the of MOFs typically comes at cost reducing area, thereby increasing conductivity. This study introduces an approach simultaneously boost porosity MOF‐based material while maintaining remarkably The electrically...
