This catalytic system contains several advantages: 1) Water, a green solvent, is used in place of volatile organic solvents; 2) the catalysis reactions could be performed without an inert gas atmosphere and with low catalyst loading; 3) the work-up procedure is simple with excellent yields; 4) the catalyst could be easily recovered and used again.
The utilized catalytic system is simple and cheap, and the use of environmentally-friendly H2O2 and the natural product limonene signify that this process can be considered as a “green process”.
A catalytic converter is required to reduce the regulated and unregulated emissions when hydrous ethanol is used for a small SI engine generator set.
So it's a “green” processing for the catalyst can be removed easily from pollution solution after being used and to be used for the next run.

How to generate electricity from car suspension?5 answersElectricity can be generated from car suspension systems using various methods. One approach is to utilize piezoelectric elements, such as Lead Zirconate Titanate (PZT), which can convert mechanical energy into electrical energy through electro-mechanical coupling. This can be achieved by placing piezoelectric stacks inside the suspension system, where the mechanical vibrations from the road excitation compress and decompress the piezoelectric disks, generating electrical energy. Another method involves using a power generating system that includes a sensing device and a permanent magnet device. The sensing device, consisting of a sleeve, sensing coil mounting support, and piston rod, detects the mechanical motion and induces electrical energy through electromagnetic induction. Additionally, an electric power generating apparatus can incorporate a valve structure to disconnect the suspension device from the energy recovery device when driving on rough roads, preventing damage to the system. These approaches offer potential for harvesting electrical energy from car suspensions, providing opportunities for low-voltage applications in daily life.
What are the ways for producing green ammonia?4 answersGreen ammonia can be produced through various methods such as plasma-electrocatalytic reaction systems, electrochemical, photocatalytic, thermochemical, and chemical looping processes.
