A new bioC/NiNPs hybrid material consisting of a highly porous biocarbon matrix (bioC)with uniformly distributed metallic nickel nanoparticles (NiNPs) of 5-70 nm in size was obtainedby a simple, cheap and environmentally friendly method. Using transmission electronmicroscopy, it has been shown that the structure of the carbon matrix preferably consists ofonion carbon with hollow capsules/pores about 5 nm in size, and graphite globules up to 200 nmin size are also present. The composite bioC/NiNPs demonstrated a high electrochemicalcapacity and its high stability within 1000 charge-discharge cycles, which makes it a promisingmaterial for use as monolithic electrodes for supercapacitors.
