The authors regret that there was an error in the Conclusions section of their article. The sentence ‘Hydrogen is generated at as high rate as 720 mL/min or 32 mmol/min for 0.5 mg of Al salt at room temperature.’ should be: “Hydrogen is generated at as high rate as 720 mL/min or 32 mmol/min for 0.5 g of Al salt at room temperature.” The authors would like to apologise for any inconvenience caused. © 2018 Hydrogen Energy Publications LLC
