Description:
Background
Currently, the cost to generate reactive oxygen species is high and non‑eco-friendly.
 
Technology Overview
The proposed invention produces a Ti/MMO and Biochar materials by materials preparation and fabrication processes. 
In this technology, reactive oxygen species such as hydrogen peroxide (H2O2) and hydroxyl radicals (OH) can be electrochemically generated by low-cost and environmentally-benign biomass-derived granular biochar for wastewater treatment. Ti/mixed metal oxide (Ti/MMO) is used as the anode and biochar is used as the cathode material. The biochar is active for both H2O2 in situ generation from O2 electro‑reduction and H2O2 activation for OH formation. The Ti/MMO is efficient to supply O2 for the cathode.
This reactor cane be used for the generation of reactive oxygen species and organic pollutants degradation.
 
Benefits
- Compared with commonly used carbon-based cathode materials, such as graphite felt, carbon felt, carbon foam, the biomass-derived biochar is inexpensive and environmentally-benign
- Compared with the existing H2O2 activation methods, especially the ferrous ions, the biochar does not require acidic conditions and does not cause secondary pollution
- Compared with electro-Fenton process which uses pure O2 as oxygen source,Ti/MMO supply O2 in situ via oxygen evolution reaction
 
Applications
- Can be used for organic pollutants degradation in wastewater
- Can be used for low-concentration H2O2 electro‑generation for on-site applications
 
Opportunity
- License
- Partnering
- Research collaboration
