Then they employed this oxidation reaction as
the anode reaction of the PEC that produces hydrogen at the cathode.
They developed a novel PEC setup with a new
anode reaction.
By doing so, they demonstrated the utility of solar energy for biomass conversion as well as the feasibility of using an oxidative biomass conversion reaction as
an anode reaction in a hydrogen - forming PEC.
Therefore, researchers are currently working to develop more efficient catalysts to facilitate
the anode reaction.
Although the purpose of the cell is not the production of oxygen,
the anode reaction is necessary to complete the circuit.
The anode reaction they employed in their study is the oxidation of 5 - hydroxymethylfurfural (HMF) to 2,5 - furandicarboxylic acid (FDCA).
This anode reaction requires less energy and is faster than water oxidation while producing an industrially important chemical product.

This interphase, inspired by a layer generated within non-aqueous batteries, protects the
anode from debilitating side
reactions, allowing the battery to use desirable
anode materials, such as graphite or lithium metal, and achieve better energy density and cycling ability.
By varying the voltage added to the system as the
reaction continues — and by using more water in the
anode and cathode chambers than in the saltwater chamber — Logan says it should be possible to reduce the salinity to the 0.8 grams of salt per litre typical of drinking water.
The researchers customized the
anode by growing the iridium oxide nanotubes on a zinc oxide surface to create a more uniform surface area to better support chemical

Inside a battery, chemical
reactions involving a material called an electrolyte cause electrons to accumulate in the negative terminal, or
anode, and flow when it's connected to the positive terminal, or cathode.
«The battery will run until the
reaction uses up the ammonia needed for complex formation in the electrolyte near the
anode or depletes the copper ions in the electrolyte near the cathode,» said Fang Zhang, postdoctoral fellow in environmental engineering.
In order to run these
reactions, researchers typically use an
anode to split water molecules into protons, electrons, and oxygen, and then feed the protons and electrons to a cathode, where they react with CO2 to make hydrocarbons.
