The researchers from MIT’s Nocera Lab, led by Dr.Daniel Nocera, claimed at the last National Meeting of the American Chemical Society that an artificial leaf has been already created and made stable in their labs.

They say that this artificial leaf doesn’t look like the natural leaf ,but it has the same inputs and outputs.

The artificial leaf is made of silicon,electronics and the chemical reactions take place in the presence of various catalysts. The sunlight is used to break water into hydrogen and oxygen as it really happens with the natural leaf,the device creating electricity in a separate fuel cell.

suggested that these cells placed in water and left in the sun could be the source of the basic electricity of a home for a day.

Other working attempts to produce photosynthesis in artificial materials are of notoriety in the chemical world,but the leap forward presented here is significant.

The Nocera Lab created a more stable artificial leaf ,not so expensive as others do, having a longer life.For example the common catalysts including cobalt and nickel do the job with far less expense. Their leaves have worked continuously for 45 straight hours without a drop in output.

The Nocera Lab’s leaf could be the key component to shifting toward a hydrogen-based economy. All the efforts of the scientific world are done in replacing the conventional technologies with types of technology providing clean, plentiful and easy-to-come-by energy.
