Background:

Two-dimensional (2D) materials enable complex porous material synthesis.
Programming spatial heterogeneity in single monolithic materials is challenging.

Purpose of the Study:

To develop a method for fabricating monolithic graphene hydrogels with controlled spatial heterogeneity.
To exploit this heterogeneity for advanced material applications.

Main Methods:

Metal-dependent gelation of graphene oxide (GO) dispersions using multimetal templates.
Interfacial electrochemical reduction driven by differences in reduction potentials.
Fabrication of freestanding graphene hydrogels without binders.

Main Results:

Monolithic graphene hydrogels with distinct regions of chemical composition, pore architecture, and hydrophobicity were produced.
Metal identity dictated GO reduction level, arrangement, and surface properties.
Spatial heterogeneity allowed for region-selective N-doping and platinum nanoparticle deposition.
Seamless integration of multiple hydrogel units into complex 3D architectures was achieved.

Conclusions:

The metal-dependent gelation platform offers a versatile strategy for programmable graphene hydrogel fabrication.
This approach enables the creation of advanced materials for electrochemical, catalytic, and energy applications.
