This paper reports a pH‐mediated hydrothermal reduction method that combines with moulding methods, allowing controllable fabrication of high density (up to 1.6 g cm −3 ) isotropic graphene macrostructures with various shapes. This “graphene” (CG) has a compressive strength of 361 MPa (6 times higher than conventional graphite products) and electrical conductivity of 7.6 S cm −1 . The processing steps are scalable.
