·The surface area of calcined HTC was ∼138 m 2 /g whereas the uncalcined HTC was ∼12 m 2 /g See SI; Fig S1 The higher surface area for calcined HTC can be a result of the decrease in HTC crystal size caused by thermal treatment as shown in related studies [23] [24] This decrease in crystal size is supported by the broadening of XRD peaks for calcined
