摘要：

A stable colloid of g-C3N4 nanosheets was prepared on a large scale via a H2SO4 exfoliation route. The amphoteric nature due to the simultaneous presence of carboxyl and amino groups provided a strategy to fabricate heterostructures by an electrostatic re-assembly between g-C3N4 nanosheets and various charged guests in different pH systems.
