Researchers break down plastic using sunlight

Researchers have developed a method to convert consumer plastic into formic acid using sunlight, as reported in Advanced Science. The process involves dissolving polyethylene in a solution with a vanadium-based catalyst and exposing it to artificial sunlight. This method is advantageous as it avoids high heat and toxic substances, offering a low-emission source of clean energy for power generation and hydrogen fuel cells.

What is the main purpose of the research team's discovery?

• To reduce the cost of plastic production

• To improve the durability of plastics

• To convert plastic into a chemical for clean power

• To create a new type of plastic

What role does vanadium play in the process described?

• It acts as a solvent

• It is used as a catalyst

• It is the main component of polyethylene

• It is a byproduct of the reaction

What is the significance of using artificial sunlight in the process?

• It helps in cooling the solution

• It increases the weight of the plastic

• It breaks carbon bonds in polyethylene

• It changes the color of the solution

What is the end product of the conversion process?

• Carbon dioxide

• Formic acid

• Methane

• Hydrogen gas

Why is formic acid considered beneficial in this context?

• It is a rare and expensive chemical

• It is a high-emission fuel

• It is used in hydrogen fuel cells

• It is a common household cleaner
