Hopcalite Catalyst Powder, primarily composed of manganese dioxide and copper oxide, has long been recognized for its efficiency in eliminating harmful gases such as ozone (O₃), carbon monoxide (CO), and volatile organic compounds (VOCs). One of the most effective methods for maximizing its performance is through uniform coating onto structured substrates, particularly ceramic or aluminum honeycombs.

 

 

 

Why Use Ceramic or Aluminum Honeycombs?

 

 

Ceramic and aluminum honeycombs are engineered substrates designed to provide a large surface area with minimal airflow resistance. Their honeycomb structure allows air to flow through evenly while maintaining close contact with the catalyst layer. When Hopcalite Catalyst Powder is coated onto these substrates, the combination delivers both high catalytic efficiency and low-pressure drop—an essential balance in modern gas treatment systems.

 

 

 

Advantages of Coating Hopcalite Catalyst Powder

 

 

1. Enhanced Surface Area Utilization

The fine particle size of Hopcalite Catalyst Powder (3–8 microns) ensures even distribution across the substrate, creating a high-density active layer. This maximizes the availability of catalytic sites for gas-phase reactions.

 

 

2. Superior Reactivity and Efficiency

Once coated, the honeycomb-supported catalyst effectively decomposes ozone and oxidizes trace VOCs such as formaldehyde, even at ambient or sub-room temperatures. This makes it particularly suitable for continuous air treatment applications.

 

 

3. Low Energy and Maintenance Requirements

Unlike thermal methods or activated carbon, Hopcalite-coated honeycombs require no external energy input and do not degrade significantly during operation. This leads to stable long-term performance and reduced maintenance intervals.

 

 

4. Structural Flexibility

Both ceramic and aluminum honeycombs can be customized to specific cell densities and geometries, allowing them to be integrated into a wide variety of air purification and exhaust treatment systems.

 

 

 

Typical Applications

 

 

Hopcalite-coated honeycombs are widely applied in:

 

• Office Equipment Emissions – Removal of ozone from printers, photocopiers, and electronic devices.

 

• Chemical Processing Exhausts – Treatment of industrial emissions containing ozone and VOCs.

 

• Indoor Air Treatment Systems – Integration into HVAC and filtration units for VOC abatement and odor removal.

 

• Water and Wastewater Facilities – Management of ozone off-gas emissions to protect workers and surrounding environments.
