(a) NaCl and Na2S crystals. (b) Glucose-coated NaCl and Na2S crystals. (c) Self-stacking of the glucose-coated NaCl and Na2S crystals (3D NaCl–Na2S@glucose), with Na2S crystals surrounded by NaCl crystals. (d) Self-stacking of GC-coated NaCl and Na2S crystals (3D NaCl–Na2S@GC). (e) 3D S@PGC composite formed through the simultaneous dissolution of the NaCl crystals and oxidation of the Na2S with Fe(NO3)3.
